#10738: insecure temp file in testcc.sh, testcxx.sh

By preparing a suitable symlink, this lets a local attacker at least
delete any user file:
{{{
[...]
TESTFILE=/tmp/hkldfz-test-for-c-compiler-6sokljkhsdhfdf.$$.c
cat >$TESTFILE <<"E*O*F"
[...]
}}}
Is there any reason for not using mktemp?
Low priority because that is only called during compile time...
