    testsuite: Remove .exe suffix in prune_gcc_output
    
    When running the testsuite under Windows, we noticed failures in
    testcase which attempt to match compiler error messages containing the
    name of the executable.
    
    For instance, gcc.dg/analyzer/signal-4a.c tries to match 'cc1:' which
    obviously fails when the executable is called cc1.exe.
    
    This patch removes the .exe suffix from various toolchain executables
    to avoid this problem.
