From the tests point of view, this is a necessary step for another
patch [1] and allows parsing macros such as "#define A | B". Without
it, a few tests [2] choke when the other patch [1] is applied:
/src/glibc/scripts/../elf/elf.h:4167: error: uninterpretable macro
token sequence: ( EF_ARC_MACH_MSK | EF_ARC_OSABI_MSK )
Traceback (most recent call last):
