[reSIProcate] building shared libraries on AMD64

["Alfred E. Heggestad" <aeh@xxxxxx>]

hi

when building resiprocate with "Should the resip libraries be built
shared?" set to "Yes", I got the following error:


/usr/bin/ld: obj.debug.Linux.x86_64/AbstractFifo.o: relocation
R_X86_64_32 against `a local symbol' can not be used when making a
shared object; recompile with -fPIC
obj.debug.Linux.x86_64/AbstractFifo.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [obj.debug.Linux.x86_64/librutil.so] Error 1


adding the "-fPIC" option solved the problem, but I am not sure if
this is the correct way to solve it.. patch below:
