Also the use of single quotes instead of double quotes as Arnout has noted.

$(PKG_CONFIG_HOST_BINARY) should output the correct list of libraries for both
static and dynamic builds. I think that the mtd.mk simplification and wider
test coverage outweighs the added overhead. Are there any other drawbacks to
running $(PKG_CONFIG_HOST_BINARY) unconditionally?
Thanks for reviewing and testing.
