[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.

      Add support for the Signal Processing Engine.  This will set up

      the toolchain so that it supports the SPE ABI extensions. This

      Setting this option will append "spe" to the end of your target
yann@1181
    15
      tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
yann@1181
    16
      configure/build system will know to include SPE ABI support.
yann@1181
    17
      It will also automatically add "-mabi=spe -mspe" to your
yann@1181
    18
      TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,
yann@1181
    19
      so you do not need to explicitly add them.
