 Sorry, I wasn’t clear. You’d use a block like this:
 {{{
 pre-build {
     build.args-append   LDFLAGS="${configure.ldflags} [exec ${prefix}/bin
 /pkg-config lua --libs]"
 }
 }}}

 Or set `build.args` all at once, if you’d like:
 {{{
 pre-build {
     build.args      CC="${configure.cc} [get_canonical_archflags]" \
                     LUADIR=${prefix}/include \
                     CFLAGS="${configure.cflags}" \
                     LDFLAGS="${configure.ldflags} [exec ${prefix}/bin/pkg-
 config lua --libs]"
 }
 }}}
 These idioms obviate the need for unnecessary patching.
