Yes, we were seeing this too:
libcap support: yes
x86_64-unknown-linux-gnu-pkg-config: warning: blocking 'libcap': not
selected by 'iproute2'
x86_64-unknown-linux-gnu-pkg-config: warning: blocking 'libcap': not
selected by 'iproute2'
finished target iproute2.prepare
but then later:

If you want to investigate more, see

(internal PTX net only).
It could be related to libcap being installed on the build host, at
least the package doesn't fail to build on systems where it isn't
installed, and there is also no HAVE_LIBCAP in iproute2-5.7.0/config.mk.
