The check for HAVE_LD_RO_RW_SECTION_MIXING fails on targets where ld

this test results in a libgcc crtbegin.o which has a writable .eh_frame
section leading to the default linker scripts placing the .eh_frame
section in a writable memory segment, or a linker warning about writable
sections in a read-only segment when using ld scripts that place
.eh_frame unconditionally in ROM.
gcc/ChangeLog:
* configure: Regenerate.
* configure.ac: Use ld -r in the check for HAVE_LD_RO_RW_SECTION_MIXING
I'm not sure that simply replacing -shared with -r is the right fix
here. ISTM that if the -shared tests fails, then we can/should try the
-r variant. Am I missing something here?
