Log:
Add sanitizer_linux_x86_64.lo if __x86_64__ is defined by $CC

Since size of "void *" is 4 bytes for x32, check if __x86_64__ is defined
by $CC, instead of

if test x$ac_cv_sizeof_void_p = x8; then

to decide wether sanitizer_linux_x86_64.lo should be used.

        Backported from mainline
        PR sanitizer/82379
        * configure.tgt (SANITIZER_COMMON_TARGET_DEPENDENT_OBJECTS): Set
        to sanitizer_linux_x86_64.lo if __x86_64__ is defined by $CC.
