If the building compiler enables no direct external data access by default, access to protected data in shared libraries from executables must be compiled with no direct external data access. If the testing compiler doesn't support it, set have-protected-data to no to disable the tests which requires no direct external data access. Add LIBC_TRY_CC_COMMAND to test a building compiler option or options with an input file. This fixes BZ #33286. Signed-off-by: H.J. Lu <hjl.tools@gmail.com> Reviewed-by: Sam James <sam@gentoo.org>
