The tests FAIL on x86_64-linux with
/usr/bin/ld: cannot find -lubsan
collect2: error: ld returned 1 exit status
compiler exited with status 1
FAIL: gcc.target/i386/pr84508-1.c (test for excess errors)
Excess errors:
/usr/bin/ld: cannot find -lubsan
The problem is that only *.dg/ubsan/ubsan.exp calls ubsan_init
which adds the needed search paths to libubsan library.
So, link/run tests for -fsanitize=undefined need to go into
gcc.dg/ubsan/ or g++.dg/ubsan/, even when they are target specific.
Tested on x86_64-linux with
make check-gcc RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} i386.exp=pr84508*
ubsan.exp=pr84508*'
and committed to trunk as obvious.
