Bootstrap compiler rebuild

[const-rs]

I've rebuilt mosml compiler with cd src; make world; cd compiler; make promote; make clean; make promote, on two different systems: ALT Linux/AMD64, Debian/mipsel32. md5sums of src/mosmlcmp were different, which is really surprising. I have also 64-bit SPARC machine, which, unfortunately can't compile camlrunm yet (but it looks like I can fix it).

Do you know why md5 sums were different?

Found out that it is probably due to 32-bit arch. I recollected that I have an access to 32bit Fedora/i386 and tried to build MosML there. MD5 sums of mosmlcmp and mosmllnk are identical to ones of Mips32 "machine" (LinkIT microcontroller).

After first make (compiler/linker are built with old bootstrap compiler) md5 sums are:

f0658ec3ce2da6ddbd7f0fad1157adde — mosmlcmp
2189234d4f9bfc2aa0d7ea0b4d3f3765 — mosmllnk
08fc27ca58a573f3ed5b0dc409ddf2df — mosmllex

I'll run make clean; make world; make promote several times and report results here. ;-)

1. These md5 sums are final - subsequent runs with new compiler do not change anything.
2. Bootstrap compiler/linker/lexer should be built on 32-bit. If it is built on 64-bit system, camlrunm from 32-bit system can't run this compiler (seg. faults).
3. If you accept - I can make PR with bootstrap compiler/linker/lexer built on 32-bit system.
