bugfix to mpfr tests + crosstool-ng patch

[Oron Peled]

Hi,

Two patches attached. The real bugfix is mpfr-2.4.1-test-tmul.patch.
However, since it touches tests/Makefile.am I had to change
./scripts/build/mpfr.sh in crosstool-ng so it would run autoreconf.

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.

Cheers,
