[PATCH] testsuite: Remove .exe suffix in prune_gcc_output

[Christophe Lyon <christophe.lyon@foss.st.com>]

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.
