Subject: fix-gnulib: Patch %reldir% too.
X-Git-Url: https://git.draconx.ca/gitweb/dxcommon.git/commitdiff_plain/5d7b80ce6f21d6d90ecec188f135e665d789dede

fix-gnulib: Patch %reldir% too.

Gnulib has recently started producing rules using %reldir%.  This
is cool but since we are postprocessing the automake fragment anyway,
we can easily substitute %reldir% ourselves which avoids requiring
newer Automake just for this.
