libcap: Append `-fPIC` to `CFLAGS` to fix compilation on newer binutils/ld.
Doing `bitbake libcap` with
PREFERRED_VERSION_binutils = "2.20"
PREFERRED_VERSION_binutils-cross = "2.20"
PREFERRED_VERSION_binutils-cross-sdk = "2.20"
PREFERRED_VERSION_gcc = "4.4.2"
PREFERRED_VERSION_gcc-cross = "4.4.2"
PREFERRED_VERSION_gcc-cross-sdk = "4.4.2"
PREFERRED_VERSION_gcc-cross-initial = "4.4.2"
PREFERRED_VERSION_gcc-cross-intermediate = "4.4.2"
in `local.conf` made `do_compile` error out with the following message [1].
arm-angstrom-linux-gnueabi-ld -soname libcap.so.1 -x -shared -o libcap.so.1.10 cap_alloc.o cap_proc.o cap_extint.o cap_flag.o cap_text.o cap_sys.o
arm-angstrom-linux-gnueabi-ld: cap_text.o: relocation R_ARM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC
Khem Raj explained it the following way [2].

Therefore just append `-fPIC` to the CFLAGS and bump the PR variable.
The strange thing is still, that other distributions seem to have patched libcap to build with `-fPIC` long ago [3–5].
