do not require gcc to build emacs on i386

emacs on i386 currently requires gcc to build because of a bug in older
versions of clang.

https://llvm.org/bugs/show_bug.cgi?id=18171

however, the bug has been fixed in clang versions that ship with 9.3 and 10.1,
the two supported freebsd releases with clang.  8.4 uses gcc.  I confirmed this
with dim@

The attached patch drops gcc requirement.  I have been using emacs for a week
built with clang with no problems.
