Patch names should not contain the version number, but instead a number
that allows patches to be applied in the right order. See
http://buildroot.org/downloads/manual/manual.html#patch-policy.

Also, while it is not written anywhere explicitly, the patch filename
should be all in lower case.

The patch should contain a description + Signed-off-by line. See
http://buildroot.org/downloads/manual/manual.html#_format_and_licensing_of_the_package_patches.

80 dashes, one empty line between header and variables.

Comment not needed.

Last line not needed.

Use $(TARGET_CONFIGURE_OPTS) directly.

DESTDIR typically not needed when building. Also, you can probably
combine this in one line:

	$(MAKE) -C $(@D) \
		$(USTR_MAKE_CMDS) all all-shared

However, there's one thing we've forgotten: we try to support static
library builds in Buildroot, when BR2_PREFER_STATIC_LIB is enabled. So
when it's possible, it'd be great if the packages could behave nicely
when BR2_PREFER_STATIC_LIB=y (by disabling the build of shared
libraries). If it's not possible or too complicated, we can add a
depends on !BR2_PREFER_STATIC_LIB.

Drop the uninstall comands.

Same comments as above, for everything :)

Thanks!
