While the fallout(*) from the libsanitizer commit is handled,
it's obvious it should have a noconfigdirs= section in
toplevel/configure.ac like the other target libs. Here's what I
committed after observing that a cris-elf build passed, where it
previously failed building libsanitizer which wrongly tries to
compile using -fPIC despite checking in its configure.ac IIUC.
But, I'd like to update the target contents there to something a
bit more generic.
Maybe disable libsanitizer everywhere except for (referring to
the three common target-related file-name parts in libsanitizer)
"mac", "win" and "linux"? Or disable everywhere except x86_64 /
i386? That's the only port that defines the required
TARGET_ASAN_SHADOW_OFFSET. Maybe the library configure.ac
should check whether using -fsanitizer is error-free and disable
the libsanitizer build automatically?
toplevel:
* configure.ac: Add section for noconfigdirs for libsanitizer.
Disable for cris-*-* and mmix-*-*.
* configure: Regenerate.

*) -fPIC passed when building libsanitizer for targets that
don't support it, lack of multilib setup for libsanitizer,
libsanitizer not installed in version-specific subdir...
Basically, IMHO it should just copy the generic
libgfortran/configure.ac and be done with it. Right now it has
the smallest configure.ac of the target-libraries.
