Re: Modula-2: merge followup (brief update on the progress of the new linking implementation)

Hi Gaius,

unfortunately, that branch doesn't bootstrap for me anywere:

* On both x86_64-pc-linux-gnu and i386-pc-solaris2.11:

libtool: compile:  /var/gcc/modula-2/11.4-gcc-modula-2/./gcc/gm2 -B/var/gcc/modula-2/11.4-gcc-modula-2/./gcc/ -c -g -O2 -g -O2 -I. -I/vol/gcc/src/hg/master/modula-2/gcc/m2/gm2-libs-min -I/vol/gcc/src/hg/master/modula-2/gcc/m2/gm2-libs -fno-exceptions -fno-m2-plugin /vol/gcc/src/hg/master/modula-2/libgm2/libm2min/../../gcc/m2/gm2-libs-min/M2RTS.mod  -fPIC -DPIC -o .libs/M2RTS.o

  and several more.

  Seems like PR modula2/101392 raised its ugly head again, after it had
  been gone for a while.  I'm currently trying sparcv9-sun-solaris2.11
  instead to see how that fares.
