Only enable it for CPUs that support it.
This restores the behavior prior to 7a650caf.

Automatically change MANGLE() into named inline asm operands when direct symbol reference in inline asm are not supported.

Group checks into logical groups and sort alphabetically within those groups
unless checks have close coupling. Keep closely coupled checks together.

SPARC is no longer being used in any multimedia-related fields and the
VIS optimizations only represent a maintenance burden.

Previously, it was an implicit dependency through mpegvideo. Change
this, as implicit dependencies can cause all sorts of trouble.

ffv1 does not use any part of the dsputil framework.

It should work best for debian stable and people not installing the .pc
file.

Should be used only to pass extra flags to pkgconf invocation,
e.g. --static.

Sort lists of components. Add some whitespace where it helps readability.
Consistently use double instead of single quotes around component lists.

The current release of version 1 uses libopenjpeg1.

The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl
libc, some BSD flavours) are not exactly representable, i.e.
(double)DBL_MAX == DBL_MAX is false
This violates (at least some interpretations of) the C99 standard and
breaks code (e.g. in vf_fps) like
double f = DBL_MAX;
[...]
if (f == DBL_MAX) { // f has not been changed yet
    [....]
}

Not guaranteed to be in nanosecond resolution. On iOS 7 the duration
of one tick is 125/3 ns which is still more than an order of magnitude
better then microseconds.

Replace decicycles with the neutral UNITS. Decicycles is strange but
tenths of a nanosecond and unspecific "deci"-ticks for mach_absolute_time
is just silly.

The SVQ3 decoder reuses large parts of the H.264 decoder so it
makes no sense to enable the former but not the latter.

Also drop unnecessary h263.o object from SVQ3 decoder object list.
