Source files built for running on the build host can be given extra
argument via the HOSTCFLAGS variable. This is evaluates in
scripts/Makefile.host and results in adding $(HOSTCFLAGS_$(target-stem).o)
during each HOSTCC invocation.
We do that correctly at all places, except for two: rsatoc and rkimage
both use openssl, but they only have HOSTLDLIBS_rsatoc correctly set for
linking against openssl. HOSTCFLAGS_ however was incorrectly set for
the targets without the .o suffix and compiling these files only worked,
because OpenSSL was installed into a directory that's in the default
include search path. This is not a given, e.g. when building barebox
through OpenEmbedded inside a container without openssl headers, so
let's ensure pkg-config is correctly used.
Fixes: 128ad3cbe043 ("scripts: Add rsatoc tool")
Fixes: 63f612f9e0ea ("ARM: Rockchip: Add rkimage tool")
