libgcc/config/t-hardfp uses sed to convert libgcc function names (like __addsf3) into a tuple of -D defines.
The regular expression used for that contains |, which is not a basic regular expression and not understood by posix sed. Gnu sed seems to enable it by default, I suppose - or this should have been noticed earlier. Many other sed implementations need -E or -r (for gnu sed compatibility), which the attached patch adds. It might be better to split the alternatives into several expressions and duplicate the right hand sides, or mix with some sh code, but this is already pretty messy. Martin
