I sent a message about this yesterday, but it does not appear to have
got to the list.
According to the attached message, mips builds for Linux should not use
-mips2 in the compilation or linking. It appears that this can be
prevented by removing the mips special case from src/template/linux.

No, the kernel doesn't always have the greatest error messages...
test.c:
main(void)
{
return 1;
}
rmurray@resume:~$ gcc -o t test.c ; ls -l t ; ./t
-rwxr-xr-x 1 rmurray rmurray 7628 Mar 20 16:43 t
rmurray@resume:~$ gcc -mips2 -o t test.c ; ls -l t ; ./t
-rwxr-xr-x 1 rmurray rmurray 7628 Mar 20 16:44 t
bash: ./t: No such file or directory
The reason this worked in the past is due to a bug in binutils -- it wasn't
setting the mips2 bit in the elf header of the binary. That bug has now
been fixed, and the kernel refuses to run anything with a mips# bit set
in the header, as it is used to indicate an irix binary, according to the
comments in elf.h.
