New build system ready for testing

Hello Sebastian,

I get a linker error when I try to build libbsd for BBB (with a buildset that builds everything but netipsec):

/home/EB/christian_m/Projekte/rtems-bbb/install/rtems/6/lib/gcc/arm-rtems6/10.2.1/../../../../arm-rtems6/bin/ld: ./libbsd.a(uipc_mbuf.c.20.o): in function `m_unmappedtouio':
/home/EB/christian_m/Projekte/rtems-bbb/libs/rtems-libbsd/build/arm-rtems6-beagleboneblack-noIPSec/../../freebsd/sys/kern/uipc_mbuf.c:1813: undefined reference to `PHYS_TO_VM_PAGE'
/home/EB/christian_m/Projekte/rtems-bbb/install/rtems/6/lib/gcc/arm-rtems6/10.2.1/../../../../arm-rtems6/bin/ld: /home/EB/christian_m/Projekte/rtems-bbb/libs/rtems-libbsd/build/arm-rtems6-beagleboneblack-noIPSec/../../freebsd/sys/kern/uipc_mbuf.c:1814: undefined reference to `uiomove_fromphys'
collect2: error: ld returned 1 exit status

Configure line for libbsd is:

./waf configure \
        --prefix=/home/EB/christian_m/Projekte/rtems-bbb//install/rtems/6 \
        --rtems-bsps=arm/beagleboneblack \
        --buildset=/home/EB/christian_m/Projekte/rtems-bbb//build/src/noipsec.ini \
        --enable-warnings \
        --optimization=2 \

Adding your patch from ages ago to libbsd works to solve that:

But you haven't applied it to the libbsd master. So I assume that there is a better workaround for that problem? What's the correct solution?

Best regards
