8e950c9b42 Merge commit 'aa37d2bf4505afc106e2a23c44afc722bb204a8e' 
* commit 'aa37d2bf4505afc106e2a23c44afc722bb204a8e':
  swscale: Kill non-compiling disabled cruft

The isGray() chunk is not merged as an alternative patch actually fixing
the dead code is currently under review on the mailing-list.

The SWS_X chunk is merged, with an additional cosmetic.

994c4bc107 x86util: Port all macros to cpuflags 
Also do some small cosmetic changes: Drop pointless _MMX suffix from ABSD2
macro name, drop pointless check for MMX support, we always assume MMX is
available in our SIMD code, fix spelling.

92db508307 build: Generate pkg-config files from Make and not from configure 
This moves work from the configure to the Make stage where it can
be parallelized and ensures that pkgconfig files are updated when
library versions change.

319438e2f2 swscale: save ebx register when it is not available 
Configure checks if the ebx register can be used for asm and it has to
be saved if and only if this is not the case.
Without this the build fails when configuring with --toolchain=hardened
--disable-pic on i386 using gcc 4.8:
error: PIC register clobbered by '%ebx' in 'asm'

In that case gcc 4.8 reserves the ebx register for the GOT needed for
PIE, so it can't be used in asm directly.

This patch addresses Trac ticket #5570. The optimized functions are in file
libswscale/ppc/input_vsx.c. Each optimized function name is a concatenation of the
corresponding name in libswscale/input.c with suffix _vsx.

8e05f9217a swscale/utils: Split scaling if possible and yuv->yuv with different matrixes is requested

directly in subsampled YUV, this is quite a bit more complicated though

Fixes Ticket4805
