[pushed,gdb/testsuite] Require -fsplit-stack in gdb.base/morestack.exp
Commit Message
On aarch64-linux, I run into:
...
gdb compile failed, cc1: error: '-fsplit-stack' is not supported by this \
compiler configuration
UNTESTED: gdb.base/morestack.exp: failed to prepare
...
Fix this by requiring -fsplit-stack, such that we have instead:
...
UNSUPPORTED: gdb.base/morestack.exp: require failed: \
expr [have_compile_flag -fsplit-stack]
...
Tested on x86_64-linux and aarch64-linux.
