[Bug binutils/11633] New: bintuils testsuit fails if built with CFLAGS="-fstack-protector-all"

[xake at rymdraket dot net]

In a updated binutils git tree:

$ CC="gcc" CFLAGS="-march=native -mtune=native -O2 -pipe -fstack-protector-all"
./configure && make -j10 && make -j10 check

<snip>
Running /home/xake/devel/testcases/binutils/ld/testsuite/ld-elfvsb/elfvsb.exp 
...
FAIL: common hidden symbol
FAIL: weak hidden symbol DSO last
FAIL: weak hidden symbol DSO first


However if I try build it with -fstack-protector or -fno-stack-protector all
checks passes fine.

The tests fails because the link command does not link with anything, but
-fstack-protector-all needs the final binary to be linked against libc, else it
will not find all its symbols.
If I add -fno-stack-protector to the CFLAGS in elfvsb.exp it also passes.

However I do not know how to write the code for runtest to make this change in a
portable and reliable way. config/default.exp has a logic to determine if it
uses gcc, should I do a similar check for elfvsb.exp and add
-fno-stack-protector to the end of CFLAGS if gcc is used??
