--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
What libiberty/{make-temp-file.c,pex-common.c} do is just unconditionally
declares mkstemps:


extern int mkstemps (char *, int);


So I think the fix should be simple as doing this:
extern "C"  int mkstemps (char *, int);

inside lto-wrapper.cc towards the top (with maybe a comment saying it is always
included in libiberty if libc does not have a definition.
