pexecute.c: Updates from gcc.

Browse Source 
* pexecute.c: Updates from gcc.  Copy in gcc has been removed.  This
        is the canonical copy.  Define ISSPACE if !IN_GCC.
        * alloca.c, vfprintf.c, choose-temp.c, mkstemp.c, getopt.c: Similarly.
        * getopt1.c, obstack.c: Similarly.
        * Makefile.in: Build mkstemp.o
