commit b2e1c26f0b62531636509fbcb6dab65617ed8331 upstream.
glibc recently did a sync up (94e73c95d9b5 "elf.h: Sync with the gabi
webpage") that added a #define for EM_METAG but did not add relocations
This triggers build errors:
scripts/recordmcount.c: In function 'do_file':
scripts/recordmcount.c:466:28: error: 'R_METAG_ADDR32' undeclared (first use in this function)
case EM_METAG: reltype = R_METAG_ADDR32;
^~~~~~~~~~~~~~
scripts/recordmcount.c:466:28: note: each undeclared identifier is reported only once for each function it appears in
scripts/recordmcount.c:468:20: error: 'R_METAG_NONE' undeclared (first use in this function)
rel_type_nop = R_METAG_NONE;
^~~~~~~~~~~~
Work around this change with some more #ifdefery for the relocations.
