When you check for a specific compiler you know that its -E option
generates PP output. But if you revert to "not GCC" you can't assume
this anymore. Hence, a small infrastructure change.

I believe we need wrappers to handle -E option. Currently, only
mk/compiler/xls.mk makes a wrapper. This is inconsistent.
