We need to use -mminimal-toc on IBM AIX
AIX's XCOFF is limited to 16k entries in its TOC for 32bit compilation,
which quickly overflows with GHC's code generation.
Otoh, the Parser.hs module contains more entries than fit into a
minimal-toc, so we need to switch back to `-mfull-toc` for that single
module again.
