libffi on solaris x64 and gcc

[Richard PALO <richard.palo%baou.fr@localhost>]

apparently although libffi now builds on solaris, there are problems 
during packaging on x64:

PLIST seems to follow what libffi.pc believes, but the build generates 
binaries in the multiarch directory lib/amd64

This seems to be an upstream problem...

are there other x64 builds suffering the same demise?
