yasm generates a warning instead of an error when "CPU amdnop" is not supported, so the check always succeeds.
HAVE_CPUNOP as true when the available yasm version doesn't support amdnop doesn't make sense.
Check http://fate.ffmpeg.org/log.cgi?time=20120901143315&log=compile&slot=x86_64-archlinux-gcc-oldyasm to see the amount of warnings it generates.

This is necessary to avoid spuriously enabling _external or _inline
variants of arch extensions when they should be disabled.

This enables replacing the -l and -L flags used to specify the
just-built libraries when linking the tools and shared libs with
non-standard syntaxes. System library flags are already handled
by the filtering mechanism in configure.

Some tools use different command line syntax for specifying output
when compiling and linking. To accomodate these, separate variables
must be used. No currently supported compilers/linkers are affected
by the change.

There is no point in having the user disable any fastdiv macros.
Besides the condition implementation was broken and only disabled
the C implementation, but no platform specific assembly versions.
For some compilers ISA older than mips32r2 is set as default.
Because of them assembler flag "-mips32r2" needs to be added
for CPUs that support mips32r2 ISA in part of configure script
where ISA capabilities are checked.
"-mhard-float" assembler flag is also added for CPUs that have FPU.

There used to be one test for Altivec intrinsics support and a
separate test to determine which of two possible syntaxes to use
for vector literals. Since 2008, we only support the more common
of these so the split test no longer makes sense.
This combines the tests into one and also changes the hard error on
failure to a warning. The test can reasonably fail if no --cpu flag
is provided (or is provided with an unknown CPU) and the compiler
default target does not support Altivec. Aborting in this case is
probably over-reacting.

Allow to select specific documentation components, and reliably check for
component dependencies.
In particular, check for perl presence on the system.
This fixes build failures on debian/kfreebsd, which has the
sctp.h header, but it is currently broken (a cpp test succeeds,
but a compile test fails), see http://bugs.debian.org/684330 for
details.
Also remove the checked item from HAVE_LIST, since the corresponding
HAVE_* define isn't used by the source code.

Some compilers do not support the Q/R modifiers used to access
the low/high parts of a 64-bit register pair. Check for this
and disable all uses of it when not supported.

This installs libraries using the proper names and locations,

Running lib.exe without parameters will always result in an error,
and failing the check.
Using the -list paramter results in a success if lib.exe is present.
Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.
