Patch to detect crashes in fixproto/fix-header and halt bootstrap

[Kaveh R. Ghazi]

The fix-header program is crashing on all my platforms this morning
(except for x86-linux which doesn't use it.)  However the bootstrap
process blithely continues on as if nothing went wrong.  I only
happened to notice it because I was looking at the screen as saw the
core dump message.

The following patch allows the bootstrap process to detect
errors/crashes from fixproto/fix-header and halt immediately so these
problems are noticed.

Tested on the following platforms which now all correctly crash and
burn on stage1 fixproto:

mips-sgi-irix6.2
alphaev5-dec-osf4.0b
sparc-sun-sunos4.1.4
sparc-sun-solaris2.7

Okay to install?

	* Makefile.in (stmp-fixproto): Acknowledge errors in fixproto.

	* fixproto: If fix-header fails, exit with an error.
