-ml and -m4 are default on sh4-unknown-linux-gnu compilers.
For 4.3.0, you could see how the default target specific options
are set with 'cc1 --target-help'. I've got the following result
on my linux box. You can compare it with your RETMS's one.
The following options are target specific:
-m4 [enabled]
-m4-100 [disabled]
-m4-200 [disabled]
-m4-300 [disabled]
-m4a [disabled]
-mb [disabled]
-mbigtable [disabled]
-mbranch-cost= 0xffffffff
-mcbranchdi [enabled]
-mcmpeqdi [disabled]
-mcut2-workaround [disabled]
-mdalign [disabled]
-mdiv=
-mdivsi3_libfunc=
-mexpand-cbranchdi [enabled]
-mfused-madd [disabled]
-mgettrcost= 0xffffffff
-mglibc [enabled]
-mhitachi [disabled]
-mieee [disabled]
-minline-ic_invalidate [disabled]
-misize [disabled]
-ml [enabled]
-mnomacsave [disabled]
-mpadstruct [disabled]
-mprefergot [disabled]
-mpretend-cmove [disabled]
-mrelax [disabled]
-mrenesas [disabled]
-mspace [disabled]
-muclibc [disabled]
-multcost= 0xffffffff
-musermode [enabled]
