Producing new gmp and mpfr versions for GCC can happen in two ways :

1. one wants to do this one at a time, building, installing and testing
   these before doing the same with bare GCC

2. building all these at the same time during the GCC build

You choosed the first way. When your target,'sparc-sun-solaris2.10', is
a 'bi-arch' target, the 32-bit host/target being the default, you should
build 32-bit versions of gmp and mpfr because the GCC binaries would be
32-bit as default.

This causes the 32-bit default being overridden...

Was the installed gcc-4.0.4 a 64-bit default one?  Why it produced 64-bit
versions for gmp and mpfr?

Of course it did... If you would like to have a 64-bit GCC which produces
64-bit binaries as default and 32-bit binaries with '-m32', then I think
your target should be 'sparc64-sun-solaris2.10' or 'sparcv9-sun-solaris2.10'.
But then maybe the 'lib's must contain 64 stuff and 'lib/sparcv7's must
contain 32-bit stuff... What does your '/usr/lib' have? Have you '/usr/lib'
and '/usr/lib/sparcv9' or '/usr/lib' and '/usr/lib/sparcv7' ?

Without any '--build=something --host=something --target=something' used
in the GCC configure, the 'something's will be guessed... These guesses
now told that you have a 32-bit opsys now, is that so?

The most easy route could have been the way '2', to symlink the gmp and
mpfr sources to the GCC sources, something like :

[root@Dell gcc-4.4.1]# ls -l gmp mpfr
lrwxrwxrwx 1 root root 12 2009-04-28 16:40 gmp -> ../gmp-4.2.4
lrwxrwxrwx 1 root root 13 2009-04-28 16:40 mpfr -> ../mpfr-2.4.0

Ie unpacking the gcc-4.4.1, gmp and mpfr sources into a common 'src'
directory and then letting the gmp and mpfr sources being seen in the
main gcc-4.4.1 src directory...
