[PATCH] m4: fix --disable-rpath for AIX

["CHIGOT, CLEMENT" <clement.chigot@atos.net>]

Currently, --disable-rpath will add directly $found_so to the compilation
line. However, on AIX, this will result on the path being hardcoded in
the built binaries.
The only way to avoid hardcoded paths without using linker flags (like
-Wl,-bnoipath) is to add -l$name.
