Bad links with *.a libs for shared objects and bad patch

[Sean McNeil]

While compiling all the ports over from i386 to amd64 arch, I found a
few I use had issues with making shared libraries with non-shared libs
that were compiled without -fPIC.

These were:

multimedia/mpeg4ip
mail/evolution

What I ended up doing to get these to build was add the following to my
/etc/make.conf temporarily to build them:

CFLAGS= -O -pipe -fPIC

Also, there is a patch to multimedia/gxine that is no good for amd64: 
files/patch-src::spidermonkey::jsprf.c

Deleting this patch will allow gxine to compile.

Cheers,
Sean
