Sorry, kind a late thought here for v4, but we don't seem to prefix many other host side tools with HOST_, i.e. LEX, YACC, AWK, PERL, PYTHON3, etc. Maybe just having the variable identifier be simply PKGCONFIG rather than HOSTPKG_CONFIG then put it at the end of the list in the top level Makefile after ZSTD (i.e. the list of host tools)? There's HOST_ prefixes when there's more than one tool involved (i.e. host compiler vs target compiler), but I suspect there's no such distinction for the existing uses of pkg-config? Otherwise, sorry for opening a bikeshed so late; this patch still LGTM.
