> --keep-system-libs, which adds a -L$(STAGING_DIR)/usr/lib to the

> breaks the build in all sort of ways as obviously building host
> binaries with the library search path pointing to $(STAGING_DIR) is
> not a good idea.
> To fix that, this commit adjusts the brltty build system so that the
> PKG_CONFIG_FOR_BUILD variable is used when using pkg-config to build
> host binaries.
