Subject: [PATCH] gettext: beat library detection into shape

For reasons which I just can't fathom gnulib doesn't use the expected tools to
find libraries but badly reinvents the wheel.  This will trivially lead to host
contamination (explicit searches of /usr/lib) or incorrect RPATHs (bad
canonicalisation resulting in relative paths).

Simply delete all the crazy, and replace with a single call to pkg-config.

Upstream-Status: Inappropriate [upstream still refuse to consider pkg-config]
