Architecture: m68k
Machine: amiga
>Description:
The libffi package builds without errors, however the generated
library references the symbol m68k_sync_icache.

dummy# nm /usr/pkg/lib/libffi.so|grep m68k
         U m68k_sync_icache

The library however only refers to libc while that symbol is in libm68k.

dummy# ldd /usr/pkg/lib/libffi.so
/usr/pkg/lib/libffi.so:
        -lc.12 => /usr/lib/libc.so.12

as a result, programs linking with libffi.so have to explicitely link
with libm68k.

>How-To-Repeat:
Building python26 for arch/amiga fails with:

/data/pkgwrk/lang/python26/work.dummy/Python-2.6.6/Modules/_ssl.c:1036: 
warning: assignment discards qualifiers from pointer target type
*** WARNING: renaming "_ctypes" since importing it failed: 
/usr/pkg/lib/libffi.so.5: Undefined PLT symbol "m68k_sync_icache" (symnum = 10)
