Modify gold testsuite to disable plugins added by GCC driver.
GCC 4.8 now adds linker plugin options by default, which conflict with the
--incremental tests in the testsuite. This patch checks whether the compiler
supports the -fno-use-linker-plugin option, and adds it to all link
commands.
2014-04-02 Cary Coutant <ccoutant@google.com>
* configure.ac (HAVE_PUBNAMES): Use C instead of C++.
(HAVE_NO_USE_LINKER_PLUGIN): Check for -fno-use-linker-plugin.
* configure: Regenerate.
* testsuite/Makefile.am (OPT_NO_PLUGINS): New macro for
-fno-use-linker-plugin.
(LINK1, CXXLINK1): Add it to the link command.
* testsuite/Makefile.in: Regenerate.
