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/baseboards/unix.exp as board description file for target. 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. ERROR: ************************************************************************ ERROR: Your compiler driver ignores -B when choosing ld. ERROR: You will not be testing the new ld in many of the following tests. ERROR: It seems you will be testing /usr/bin/x86_64-w64-mingw32-ld instead. ERROR: ************************************************************************ WARNING: Assuming target board is the local machine (which is probably wrong).
