Several tests in libgomp testsuite are quite big to have multiple partitions
(but currently they are tested without -flto), e.g. for-3.c

$ make check-target-libgomp RUNTESTFLAGS="c.exp=for-3.c --target_board=unix/-flto/-save-temps"
$ ls ./x86_64-unknown-linux-gnu/libgomp/testsuite/for-3.exe.ltrans*.o | wc
32
