pkg-config

[Sebastian Huber]

Hello,

we should think about what variables should be exposed by the pkg-config 
file. Currently, it contains a lot of things, e.g. warning and 
optimization flags. The seem to be necessary for the libbsd:

/build/rtems/5/lib/gcc/arm-rtems5/7.4.1/../../../../arm-rtems5/bin/ld: 
./libbsd.a(uipc_mbuf.c.24.o): in function `m_unmappedtouio':
/scratch/git-rtems-libbsd/build/arm-rtems5-xilinx_zynq_a9_qemu-everything/../../freebsd/sys/kern/uipc_mbuf.c:1813: 
undefined reference to `PHYS_TO_VM_PAGE'
/build/rtems/5/lib/gcc/arm-rtems5/7.4.1/../../../../arm-rtems5/bin/ld: 
/scratch/git-rtems-libbsd/build/arm-rtems5-xilinx_zynq_a9_qemu-everything/../../freebsd/sys/kern/uipc_mbuf.c:1814: 
undefined reference to `uiomove_fromphys'

Without the -Wl,--gc-sections the libbsd link fails.
