This in particular ensures that -DPIC is set appropriately for YASM, which avoids
linking failures on x86_64 for compilers that have PIE enabled by default
(e.g. hardened Gentoo).
It also makes the macho64 special-case hack adding -DPIC to YASMFLAGS obsolete.

and -DPIC makes little sense without -fPIC or similar - if -fPIC is
enabled by default, libavutil/internal.h defines PICi anyway.

This covers the previous case of x86_64 and shared, but also
works with --enable-pic.
For 32 bit x86 it currently makes no difference since x86inc.asm
ignores -DPIC for non-x86_64.

At least for cross-compilation with Gentoo gcc 4.4.2 it fixes the build errors
due to GPREL 22 being insufficient for the .bss size of > 4 MB without it.
Why these errors do not appear with static builds is unclear, it is not due
to PIC (shared builds with PIC disabled show the same issue).

Recent versions of gcc generate movw/movt pairs, and the linkers fail
to handle the associated relocations properly. Those responsible at
Codesourcery have refused to consider fixing this. Blame them for
making shared libraries slower than they need to be.

ebx_available if both "b" constraint and exb clobber code compile.
This is to fix compilation with Mac OSX 10.5.8's gcc 4.0.1 in 64
bit mode (-m64) which only fails for ebx/rbx clobbers but not
"b" constraints - this is probably a compiler bug.
Originally committed as revision 20107 to svn://svn.ffmpeg.org/ffmpeg/trunk
The test using clobber incorrectly indicates ebx to be available with the
default compilers on OpenBSD 4.5 and Haiku.

Apparently some versions of armcc do not identify as RVCT. This
changes the test to a string used by all versions.

Remove gcc-specific hacks and allow filling relevant information for non-gcc
compilers in configure.

As a sideeffect this moves more interesting variables to the top of config.mak.

if the "shared" var has not been explicitely enabled, rather than if
it has been explicitly disabled.
This way is not necessary to explicitly disable shared libraries in
order to have a pc file usable with only static libraries.

libx264 recently started mangling the name of x264_encoder_open() to
prevent version mismatches, breaking our test. Checking for another
function instead makes it work again.
