[PATCH 2/3] gdb/testsuite: wrap rustc in cc-with-tweaks.exp

[simon.marchi@polymtl.ca]

From: Simon Marchi <simon.marchi@polymtl.ca>

I noticed that the gdb.rust/* executables did not contain a .gdb_index when
run with the cc-with-gdb-index board.  This is because cc-with-tweaks.exp
does not wrap RUSTC_FOR_TARGET yet.

Wrap RUSTC_FOR_TARGET too, the same way as for the other compilers.

I can now see a .gdb_index in the produced executable.  I do not see a
difference in the test results, which I guess is a good sign.
