AX_GCC_FUNC_ATTRIBUTE detect attribute feature by compiler warnings.
Custom or unrecognized CFLAGS can causes extra warnings so attribute
check failed.
Reset CFLAGS and restore after AX_GCC_FUNC_ATTRIBUTE call.

See gnulib a512e041120e9012e69afa2f5c3adc196ec4999a:
glibc 2.25 is deprecating the namespace pollution of <sys/types.h>
injecting major(), minor(), and makedev() into the compilation
environment, with a warning that insists that users include
<sys/sysmacros.h> instead. However, because the expansion of
AC_HEADER_MAJOR didn't bother checking sys/sysmacros.h until after
probing whether sys/types.h pollutes the namespace, it was not defining
MAJOR_IN_SYSMACROS, with the result that code compiled with -Werror
chokes on the deprecation warnings because it was not including
sysmacros.h.

struct stat in libc for Linux kernel contains few fields more since 14+
years [1]. From bits/stat.h:
```
struct timespec st_atim; /* Time of last access. */
struct timespec st_mtim; /* Time of last modification. */
struct timespec st_ctim; /* Time of last status change. */
# define st_atime st_atim.tv_sec /* Backward compatibility. */
# define st_mtime st_mtim.tv_sec
# define st_ctime st_ctim.tv_sec
```
The conventional fields became an alias.
POSIX.1-2008 made struct stat st_[acm]tim mandatory [2].
OS takes care to initialize struct stat properly [3]. By not using an OS
syscall or a libc wrapper to fill struct stat, we have to take care of
initializing all fields (or at least those being used later) explicitly.

This is a preliminary step before being able to write tests for our rpm helper.
We introduce 'rpm2tags', a tool for converting RPM packages to parsable text
files. This will enable us to write tests that can run even where the 'rpm'
program isn't installed.

We introduce a mechanism by which tests can easily access configure-time
parameters (like @PERL@, @AWK@, ...).
It works by "sourcing" a file named config.sh (residing in the build tree):
. "$MC_TEST_EXTFS_CONFIG_SH"
$PERL -e 'print "hello"'
(Although config.sh has a shell syntax, Perl and Python programs too can
benefit from it, because it can be sourced into an .env_vars file and the
values exported from there.)
Of course, one can also use the traditional method, of *.in files listed in
configure.ac, but the mechanism introduced here is a more comfortable approach.

We introduce 'mc_parse_ls_l', a tool for parsing file-listings in format
similar to that of 'ls -l'. This format is used by the various extfs helpers.
We'll use this tool, in the next commit, to build a tester.

On systems where 'mode_t' is smaller than 'int', doing 'va_arg (ap, mode_t)' is
wrong because of C's "default argument promotions". GCC 4 creates crashing code
in this case.
The "va_arg" page of Gnulib's manual describes the problem and a simple solution:
https://www.gnu.org/software/gnulib/manual/html_node/va_005farg.html
However, since that solution reportedly (see thread at next link) still causes
GCC to print warnings (for no good reason; perhaps this was fixed in newer
GCCs), we pick a solution that defines a PROMOTED_MODE_T at the configuration
stage:
https://lists.gnu.org/archive/html/bug-gnulib/2009-05/msg00231.html
(We take our 'mode_t.m4' from the most recent Gnulib source.)
(If any of the URLs above no longer works, simply search the web for the
mentioned words.)

* AC_HEADER_TIME
* AC_HEADER_DIRENT
* AC_CHECK_FUNCS of isascii, statfs, sysconf, tcgetattr, tcsetattr, ftruncate

AC_C_CONST is obsolete, today it is safe to assume all C compilers
support at least C89.

Fix of exec_prefix expansion and usage.
Some distros use autoconf site scripts resourced via $CONFIG_SITE
environment varaible. That scripts are defined variable libexecdir
as
libexecdir='${exec_prefix}/lib'
In this case, EXTHELPERSDIR variable is generated wrongly, because
the 'exec_prefix' variable isn't expanded.

Due to date formatting, uc1541 extfs plugin is unusable, even tough the date formatting,
which is the one cause of the problem is coherent with the attached documentation (MM-DD-YYYY hh:mm).
Another problem with uc1541 script is connected rather with legal characters used in filename
rather than with script itself - in PET ASCII it is perfectly fine to use slash "/" character
in filenames, and as a side effect all files containing slash inside d64 image are represented
as directories on MC.
