Log Message:
Most packages that link with skalibs fail configure if the current
platform tuple doesn't match the one skalibs was built with. In pkgsrc,
this almost certainly means the OS has been updated, and almost
certainly doesn't need to break anyone's update builds. Explicitly pass
the contents of ${PREFIX}/lib/skalibs/sysdeps/target as the --target of
those configure scripts, then make sure we don't cross-compile.

skalibs-using packages not needing this workaround can define
SKALIBS_TOLERATE_TARGET_SKEW=no.
