Your pure pkgconf case is using the host icu-i18n, that's why the -L flag is
missing. The host icu-i18n doesn't have a -L bit in its Libs: stanza.
You should compare:
1) pkgconf case
PKG_CONFIG_LIBDIR=$STAGING_DIR/usr/lib/pkgconfig
PKG_CONFIG_SYSROOT_DIR=$STAGING_DIR/sysroot output/host/usr/bin/pkgconf --libs
icu-i18n
-licui18n -L$STAGING_DIR/usr/lib -licuuc -licudata
2) Real pkg-config case:
PKG_CONFIG_LIBDIR=$STAGING_DIR/usr/lib/pkgconfig
PKG_CONFIG_SYSROOT_DIR=$STAGING_DIR/sysroot /usr/bin/pkg-config --libs icu-i18n
-licui18n -licuuc -licudata
We switched from pkg-config to pkgconf because it builds a whole lot faster
(pkg-config has a whole lot of dependencies). Obviously we give up features with
that, but this is the first one where I think it is an important feature that
we're missing.
