armv7, building p7zip and -fPIC

[Guy Yur]

Hi,

Does armv7 need -fPIC when compiling?

Building archivers/p7zip fails with:
/usr/bin/ld: 7zEncode.o(.text+0x2d04): unresolvable R_ARM_MOVW_ABS_NC
relocation against symbol `_ZTIi@@CXXABI_1.3'
/usr/bin/ld: final link failed: Nonrepresentable section on output
c++: error: linker command failed with exit code 1 (use -v to see invocation)
*** [../../../../bin/7z.so] Error code 1

make[3]: stopped in
/usr/wrkdir/usr/ports/archivers/p7zip/work/p7zip_16.02/CPP/7zip/Bundles/Format7zFree
1 error

If I add "CFLAGS_armv7= -fPIC" in the port Makefile it builds fine.
The port has -fPIC for aarch64, amd64, powerpc and sparc64.

Is it a difference from armv6?
When I previously built for armv6 it worked without the option.

Thanks,
Guy
