* Always use objcopy -O (--target doesn't make sense)
and isn't available on freebsd
* No efi-bsdrv target (but has efi-app)(bug in binutils??)
* Sync linker scripts (all features are supported)
* Use clang as HOSTCC (there is no default gcc)

Commit 625bdb6368 reorganized the apps list but
also duplicated route80h.efi so remove the extra one, as having two instances
produces an error when running 'make install'.

The EFI subsystem and application entrypoint were not being set for MinGW builds
and we don't need to go through objcopy either, so fix that.
Also make sure that the link options can be understood by the compiler, which
is what we use for linking, and remove the extra GNU_EFI_USE_MS_ABI, that was
already automatically added.

To builds the apps with MinGW, the CRT0 library must be ignored because
it is ELF specific and we don't need to go through ELF relocations.
We also apply the GNU_EFI_USE_MS_ABI (since we have it), remove the -z
flags, that are invalid in MinGW, and clean up the apps Makefile.
Note that setjump and debughook are excluded from MinGW builds as they
use constructs that are not available there.

This makes our "make clean" commands show what they've /removed/, rather
than what the shell code that will be run is.

This makes setup and teardown functions defined with
__attribute__((__constructor__) and __attribute__((__destructor__)) work
in normal circumstances in EFI binaries.
A couple of notes:
- it implements both the old-style .ctors/.dtors methods and the newer
style .init_array/.fini_array ELF constructor and destructor arrays,
processed in the order:
.init_array[]
.ctors[]
efi_main()
.dtors[]
.fini_array[]
- Destructors will only be called if efi_main() exits using "return";
any call to Exit() will still longjmp() past them.
- InitializeLib() has already been called before constructors run, so
they don't need to call it (and neither does anything else.) For
compatibility, it has been altered so calling it more than once is
safe.
- No attempt is made to handle any constructor or destructor with a
prototype other than "void func(void);", but note that InitializeLib
has been called, so LibImageHandle, ST, BS, and RT are set.
- The init_array/ctor/dtor/fini_array lists aren't the using the GNU
"CONSTRUCTOR" output section command, so they don't start with a size.
- The lists are individually sorted during the link stage via
SORT_BY_NAME() in the linker script.
- The default (empty) init_array/ctor/dtor/fini_array lists are padded
out to 8-byte alignment with ".p2align 3, 0", and each list always has
at least one ".long 0" at the end of it (even if it's completely
empty). As a result, they can have NULLs that need to be skipped.
The sections they're in are mergeable, so the NULLs don't have to be
exclusively at the end.
- The ia64 and mips64el arches have not been tested.

Create a new directory called $APPSDIR
which is the default install location of
these examples. apps must be ordered after
gnuefi target.

This adds bltgrid and lfbgrid, which draw checkerboards using GOP's
Blt() and linear framebuffer, respectively, and adds some error checks
to modelist.efi.

all of our linker scripts:
_text
_etext
_text_size
_data
_edata
_data_size
There are various things that are slightly different (positions of
.rela*, .dynamic, and similar in relation to .data), but _text and _data
are now always at the beginning of their respective sections with regard
to how a debuger would reference the debug info, and _etext and _edata
are now always extant and guaranteed to be after any of the respective
kind of data the debugger would look for in that section.
This also adds an application example of how it might be used, and a
makefile target for %.efi.debug which will generate a separate debuginfo
file for that example.
This also enables debugging by default (i.e. -g is in CFLAGS) and adds
.note.gnu.build-id sections to our .so files (i.e. --build-id=sha1 is in
LDFLAGS).

users, and it seems to make more sense to put it here than in
the application.
All of these are derived from the Tiano code, but I re-wrote the
x86_64 one because we use the ELF psABI calling conventions instead
of the MS ABI calling conventions. Which is to say you probably
shouldn't setjmp()/longjmp() between functions with EFIAPI (aka
__attribute__((ms_abi))) and those without.
