configure: error: in `/opt/bw/build/gcc-4.7.4_OpenBSD_alpha_21164.002/alpha-unknown-openbsd7.8/libgomp'

Well this is now past the point of annoying in that I really do not know 
why GNU ld can not locate crt1.o for GNU OpenMP Runtime Library. Seen in
stage1 bootstrap for libgomp :

However the compiler seems to be fine and it is the GNU linker that is 
confused in some way. The compiler in question is the result of stuff
happening in stage1 :

centauri$ ls -la gcc/xgcc
-rwxr-xr-x  1 dclarke  devl  1781989 Apr 10 13:57 gcc/xgcc

If I put that directory into my PATH and then try to use xgcc we see :

$ cat hello.c

#include <stdio.h>
#include <stdlib.h>

int
main ( int argc, char **argv )
{
     int j = 314159265;

     fprintf(stderr,"hello and this is not pi = %i\n", j);

     return EXIT_SUCCESS;
}

Of course there is a pile of stuff missing in terms of those include 
directories however we do get a valid asm file hello.s and can even
produce an object file :

$ xgcc -std=iso9899:1999 -pedantic -O0 -c -o hello.o hello.c
$ echo $?
0

The OpenBSD 7.8 system provided linker is where I see the problem :

$
$ which ld
/usr/bin/ld
$ ld --version
GNU ld version 2.17

$
$ xgcc -std=iso9899:1999 -pedantic -O0 -o hello hello.c
/usr/bin/ld: crt1.o: No such file: No such file or directory
$

Why crt1.o and not crt0.o ? Those files do exist :

$ ls -l /usr/lib/crt*.o
-r--r--r--  1 root  bin  2568 Oct  9  2025 /usr/lib/crt0.o
-r--r--r--  1 root  bin  4403 Oct  9  2025 /usr/lib/crtbegin.o
-r--r--r--  1 root  bin  4717 Oct  9  2025 /usr/lib/crtbeginS.o
-r--r--r--  1 root  bin  1361 Oct  9  2025 /usr/lib/crtend.o
-r--r--r--  1 root  bin  1257 Oct  9  2025 /usr/lib/crtendS.o
$

As root I can just make a copy :

centauri# cp -p /usr/lib/crt0.o /usr/lib/crt1.o

Then we hit the next file needed "crti.o".

Those files do not exist anywhere in the build directory. Is there a way
forwards from this ?
