I tried some tricks (used ranlib from the dos-djgpp) and finally got a 
libgcc.a but it was buggy.

Q: Why not use the libgcc.a from the djgpp distribution ?
   Should the cross compiled library be different ?

To be precise: 
I don't mind using GNU make (in fact I use it most time). AFAIK gcc 
doesn't build well with other make programs (?) but it should be 
possible to use a GNU make which is not named "make". e.g. our 
GNU make programs are usually called "gmake" .

GNU make has a builtin variable called MAKE that contains the actual
name of the make program. This should be used in the makefile to start
sub-makes with the correct make program.

Otherwise you start the toplevel makefile with GNU make and all other
sub-makes with whatever "make" is first in your path (usually /bin/make).
