Hmm, (ab)using the PKG_CONFIG variable that way is probably problematic. If my 
impression serves, PKG_CONFIG is occasionally set to 
{cross-compile-tools}-pkg-config in some cross-compiling workflows. For 
example, on my work machine (which is windows 10 with a Ubuntu environment 
inside...), there are 

/usr/bin/i686-linux-gnu-pkg-config
/usr/bin/i686-w64-mingw32-pkg-config
/usr/bin/x86_64-linux-gnu-pkg-config
/usr/bin/x86_64-pc-linux-gnu-pkg-config
/usr/bin/x86_64-w64-mingw32-pkg-config

for cross-compiling for windows on linux (I know, this is bizarre, 
cross-compiling for windows inside the ubuntu environment inside windows 10 :-) 
) . On my home machine, in addition to these, I have also 
i386/ppc/x86_64-apple-pkg-config . They are used at some point in the middle of 
building the freetype backend of fontval for non-linux's.
