Test that gcc -B picks up new ld
gcc configured using --with-ld always uses that particular version of
ld if it exists. This patch adds a check that the ld version reported
directly from ld-new matches that reported via gcc. I chose to
compare the ld --version output rather than a more strict test (for
example by gcc --print-prog-name=ld), because the version test allows
a user to run the ld testsuite after installing a new ld (in the place
expected by gcc).
Sample output:
Running target unix

Using /usr/share/dejagnu/config/unix.exp as generic interface file for target.
Using /home/alan/src/binutils-gdb/ld/testsuite/config/default.exp as tool-and-target-specific interface file.
