GCC just fails to emit the offending functions and then the link fails: [ 36%] Linking C executable rtl_power CMakeFiles/rtl_power.dir/rtl_power.c.o: In function `fix_fft': rtl_power.c:(.text+0x41a): undefined reference to `FIX_MPY' rtl_power.c:(.text+0x445): undefined reference to `FIX_MPY' rtl_power.c:(.text+0x476): undefined reference to `FIX_MPY' rtl_power.c:(.text+0x49d): undefined reference to `FIX_MPY' collect2: error: ld returned 1 exit status You should be able to reproduce this really easily by building with -O0. Admittedly it's fairly bloody stupid to use -O0 for rtl-sdr but for the MIPS target this was even happening with -Os, which is slightly saner.
