It was reported that cond.m4 in gnulib is a name clash with
cond.m4 provided by Automake, where they are for completely
different purposes instead of different versions of the same macros.
A quick survey of all the macro files in the build directory reveals that
this is the only case where the gnulib copy is signficantly smaller
than the rest of the copies of the same macro name
distributed in the rest of the build system,
and the only one that name clashes with Automake.
A previous fix added a prefix to all macros from gnulib,
but the name must match how it is described in the respective modules files
as a functional requirement to build certain tools for certain (older) hosts,
so patch the problematic module instead of renaming all macros from gnulib.
