Object Splitting and the Base Package Makefile

[Wolfgang Thaller]

When building the library archive libHSbase.a, the makefile system 
includes not only all the split object files, but also the file 
PrimopWrappers.o. Consequently [at least on Mac OS X], ranlib generates 
a warning about duplicate symbols and fails to generate a sorted symbol 
table for the library (it generates an unsorted symbol table instead, 
which leads to slower linking).
Happens with the current HEAD.

Cheers,

Wolfgang
