x86: Set have-protected-data to no if unsupported

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.
