This version is OK with the indentation in math/Makefile fixed to match 
the surrounding lines, presuming x86_64 and x32 are indeed mutually 
exclusive conditions for the purpose of this multilib selection.

*But* there could be potential interactions with Zack's patch 
<https://sourceware.org/ml/libc-alpha/2019-02/msg00446.html> to tokenize 
installed headers to check for obsolete typedefs, since that of course is 
tokenizing headers as C and this is adding a Fortran header to the 
installed headers.  (The existing check-installed-headers tests skip 
bits/* so wouldn't be affected.)  So maybe we should have a way to 
distinguish Fortran headers, or maybe no problems arise in practice from 
tokenizing this one as C and the new Python test could change to skip such 
headers (it already has checks for particular header names that shouldn't 
be checked) if they cause problems in future.
