libtool: Fix $wl setting for tcc on GNU systems

(This addresses http://bugs.debian.org/663945.  See there for
more-detailed discussion.)

tcc gained support for "-Wl,-rpath -Wl,<directory>" in its
commit 7fb0482a ("Support linker options passed in several -Wl
param", 2012-03-14) but libtool doesn't know to use it.  Teach
it.

Without this change, running "make check" on MPFR when it has
been built with tcc and shared libraries doesn't work because
libtool generates a -rpath option, which tcc doesn't support.
