 So instead of trying to fix this, can we ask why
 this is a problem at all?
 
 We never enforce the absence of extra whitespace
 in CFLAGS (and almost in any other variable).
 Cases like "+=" definitions without a preceding
 "=" definition can easily cause this.
 
 Also, having extra blanks before, after or in
 between flags is valid for almost every
 application I have seen. AFAIK, this very issue
 comes from an autoconf idiosyncrasy to match
 CFLAGS in a broken way and spill out some cache-
 related errors.
