Overflown relocs in ghci

[Sigbjorn Finne]

Hi,

it looks as if you're running into a GNU ld/BFD bug
where it emits bogus PE object files that have more than
0xffff relocations. The last time I looked this bug still
wasn't fixed in the BFD codebase & there wasn't any
noticeable interest in fixing it when I reported the bug
a year or two ago.

The workaround is to split up the .o files that make up
your package into two or more .o's, along the lines of
how the "base" package does it.
