For some reason, the build fails when using GCC 4.7 due to the implicit
-finline-functions option passed to the compiler when -O3 is enabled,
which does not happen in newer versions of GCC, probably due to some of
the "General Optimizer Improvements" included in 4.8 (see [1]).
Fortunately, we don't need to disable -finline-functions completely but
just do it for "small functions", which is what this patch does.

The x32 architecture uses and ILP32 (32 bit ints, longs and pointers)
on an x86_64 CPU. Since the CPU is x86_64 we need to set FLAC__CPU_X86_64
even though the pointer size is 32 bits.

* Correct definition of FLAC__HAS_X86INTRIN in config.h file.
* Correct comparison of sse_os with 'true' instead of 'yes'.

The '-g' was in-correctly getting zapped from all CFLAGS expressions
including eg:
-mfloat-gprs=double (for powerpc e500) -> -mfloatprs=double.

* Removes FLAC__lpc_restore_signal_asm_ppc_altivec_16*
from lpc.h and stream_decoder.c
* Removes PPC-specific code from cpu.c and cpu.h
* Removes PPC stuff from libFLAC/Makefile.lite and build/*.mk
* Removes as/gas/PPC-specific stuff from configure.ac and
libFLAC/Makefile.am*
* Removes libFLAC/ppc folder and remove "src/libFLAC/ppc*/Makefile"
lines from configure.ac

Previously CFLAGS had a -O3 at the start and a -O2 at the end. According
to the GCC docs:
https://gcc.gnu.org/onlinedocs/gcc-4.9.1/gcc/Optimize-Options.html
"If you use multiple -O options, with or without level numbers,
the last such option is the one that is effective" which means that
GCC doesn't try to use SIMD to vectorize the code, etc."
This reverts commit 151739921b74fbf31420358a5fbeb094efa017ed.
This patch only when part way to replace all FLAC_* with FLaC_*
and its really not worth going all the way.
Autoconf detects the Clang compiler as GNU GCC (clang sets defines like
__GNUC__ etc) but Clang is *not* completely compatible. If we detect
Clang we set ac_vc_c_compiler_gnu to 'no'.
When compiling for ia32 on an x86_64 kernel, the configure script
was not detecting the ability to do asm optimisations because the
configure script was detecting the x86_64 kernel not the ia32
user space.
Libraries that are used internally by libFLAC(++) but are not part of
their API should be listed in pkg-config "private" clauses. Otherwise
executables that are linked dynamically against libFLAC(++) will have
unneeded direct dependencies (overlinking).
Based on a patch by Brad Smith from
https://sourceforge.net/p/flac/bugs/397/
that I updated to only include ogg if libFLAC is actually built with
ogg support.

This option is disabled by default because it is known not to work
on FreeBSD 9.1 and for Linux -> Windows cross compiling using the
Debian MinGW-w64 tool chain.
It is known to work for native compiles in Debian testing and
OpenBSD 5.2.
