In general, the custom section support in compiler needs a lot of improvement...

Try the following, maybe it could work:

procedure anyname; assembler; nostackframe;
asm
    .section ".reset,\"ax\", at progbits"
.globl _reset
_reset:                                   // <-- correct name here
    la  $k0, _startup
    jr  $k0
    nop
.text
end;
