I compiled an executable on this platform:

    % uname -a
    IRIX64 hostname 6.2 03131016 IP19

using gcc version 2.7.2

On another Irix 6.2 machine, the executable fails to run (I have
no uname output for that machine).  When I do a 'file' command on
my executable, I get:

a.out:          ELF 32-bit MSB mips-2 dynamic executable MIPS - version 1

Compiling with various compilation flags, I get:
% gcc -mips1 test.c
% file a.out
a.out:          ELF 32-bit MSB mips-2 dynamic executable MIPS - version 1
% uname -a
IRIX64 shellx 6.2 03131016 IP19
% gcc -v
Reading specs from /usr/local/lib/gcc-lib/mips-sgi-irix5.3/2.6.3/specs
gcc version 2.6.3
% gcc -mips2 test.c
% file a.out
a.out:          ELF 32-bit MSB mips-2 dynamic executable MIPS - version 1

% cc -mips1 test.c
% file a.out
a.out:          ELF 32-bit MSB mips-2 dynamic executable MIPS - version 1
% cc -mips2 test.c
% file a.out
a.out:          ELF 32-bit MSB mips-2 dynamic executable MIPS - version 1
% cc -mips3 test.c
% file a.out
a.out:          ELF 64-bit MSB mips-3 dynamic executable MIPS - version 1
% cc -mips4 test.c
% file a.out
a.out:          ELF 64-bit MSB mips-4 dynamic executable MIPS - version 1


According to the online docs, using the '-mips1' flag should generate
an executable that runs on all SGI platforms, but I can't seem
to get any compilre to produce an executable whose file type is
'ELF 32-bit MSB mips-1 dynamic executable MIPS - version 1'.
Is there anything else to do to generate a 'lowest common denominator'
executable?  How do I get a compiler to generate a
'ELF 32-bit MSB mips-2' executable?  Thanks in advance.
