For some odd reason, the new pkg-config 1.5.3 changed the behavior of
"pkg-config --version": as soon as another argument than "--version"
is passed, the code assumes the user wanted to run "--modversion"
instead.
Sadly, this breaks badly with our pkg-config wrapper that
unconditionally passes --static to pkg-config when
BR2_STATIC_LIBS=y. When ffmpeg calls "pkg-config --version" to test if
pkg-config is available and functional, it's actually "pkg-config
--static --version" that gets executed. pkg-config assumes that the
user wanted to use --modversion and bails out with an error.
This causes a build failure of ffmpeg in BR2_STATIC_LIBS=y
configuration.
This misbehavior of pkg-config has been reported upstream at
https://git.dereferenced.org/pkgconf/pkgconf/issues/19, but until it
gets fixed, we work around the issue by reverting the commit that does
the "hey let's assume you're using --modversion if --version is passed
with more than one argument".
Fixes:
http://autobuild.buildroot.net/results/ed82a95e1866ea2caadbb3433b2a255b2cf621d2/
(and plenty of other ffmpeg + BR2_STATIC_LIBS=y build failures)

Changes since v1:
- Revert the problematic upstream commit instead of doing a workaround
specific to the -static option.
