[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.

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

    11       Say 'Y' here if you want to build those two libraries specifically
    12       for crosstool-NG.
    13 
    14       The packages that can use GMP and MPFR are:
    15         - binutils
    16         - gcc
    17         - gdb

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