linux/export: fix reference to exported functions for parisc64

Browse Source 
John David Anglin reported parisc has been broken since commit
ddb5cdbafa ("kbuild: generate KSYMTAB entries by modpost").

Like ia64, parisc64 uses a function descriptor. The function
references must be prefixed with P%.

Also, symbols prefixed $$ from the library have the symbol type
STT_LOPROC instead of STT_FUNC. They should be handled as functions
too.
