[complib:mpfr] Fix building MPFR in some weird cases

The tmul test uses a compiled-in input file in $(srcdir).
The problem is that the Makefile passes it unquoted. The C code
tries to stringify it using clever macros, which may *usually* work.

In my case the source directory was named:
.../toolchain-powerpc-e500v2-linux-gnuspe-1.0-2.fc10/.../tests
And guess what? During testing I found out the program fails because
it tries to open:
.../toolchain-powerpc-e500v2-1-gnuspe-1.0-2.fc10/.../tests

Yes, CPP tokenized the macro before stringifying it and not surprisingly
the 'linux' part was converted to 1.
[on Fedora-10: cpp (GCC) 4.3.2 20081105 (Red Hat 4.3.2-7)]

So the attached patch simplify the macros and pass the path as string
from the Makefile.

      Recent gcc needs both GMP and MPFR to build some frontends.

      Say 'Y' here if you want to build those two libraries specifically
yann@602
    12
      for crosstool-NG.

        - gcc

      Also build libraries for the target. This can be usefull if you want
yann@602
    27
      to later build a compiler that will run on the target, or if you want
yann@602
    28
      to run gdb natively on the target.
