We use the non-POSIX 'local' keyword in just two places in configure;
rewrite to avoid it.

In do_compiler(), just drop the 'local' keyword.  The variable
'compiler' is only used elsewhere in the do_compiler_werror()
function, which already uses the variable as a normal non-local one.

In probe_target_compiler(), $try and $t are both local; make them
normal variables and use a more obviously distinct variable name
for $t.
