Comment (by Gcenx):

 Yes the crossfiles are undesirable due to this but that's meson.

 I decided to properly test out meson when patched with
 {{{allow_default_for_cross=True}}}

 {{{
 [target_machine]
 system = 'linux'
 cpu_family = 'x86'
 cpu = 'i386'
 endian = 'little'

 [binaries]
 c = '/usr/bin/clang'

 As can be seen from these results pkg-config is not found when cross-
 compiling for a different target, it's only found if both host and target
 match.
