Duh, instead of --rpath I used --library-path and it got me further


Free Pascal Compiler version 3.0.4 [2018/10/07] for mips

Target OS: Linux for MIPSEB
Compiling lgmounter.pas
Assembling lgmounter
Linking lgmounter

did you forget -T?

Then I modified link.res to reference crti.o

$ mips-linux-gnu-ld link.res
/usr/bin/mips-linux-gnu-ld: warning: link.res contains output sections; 
did you forget -T?

Did the same for crtn.o
