testsuite: Fix false FAIL for gdb.base/morestack.exp
Since
[commit] [testsuite patch] Fix gcc_compiled for gcc 6 & 7
https://sourceware.org/ml/gdb-patches/2016-10/msg00620.html
there has started running again
Running gdb/testsuite/gdb.base/morestack.exp ...
+FAIL: gdb.base/morestack.exp: continue
+PASS: gdb.base/morestack.exp: up 3000
but as you can see it FAILs now - on Fedora 24 x86_64 (although for example it
still PASSes on CentOS-7.2 x86_64).
Program received signal SIGSEGV, Segmentation fault.

This apparently is due to - man gcc - -fsplit-stack:
When code compiled with -fsplit-stack calls code compiled without
-fsplit-stack, there may not be much stack space available for the
latter code to run. If compiling all code, including library code,
with -fsplit-stack is not an option, then the linker can fix up these
calls so that the code compiled without -fsplit-stack always has
a large stack. Support for this is implemented in the gold linker in
GNU binutils release 2.21 and later.

* gdb.base/morestack.exp: Try to build it using -fuse-ld=gold first.
