[Buildroot] [PATCH] lttng-babeltrace: fix build with standalone gettext

[Max Filippov]

lttng-babeltrace can't detect that uuid_generate is provided by -luuid
because the configure test fails with the following message:
  libuuid.a(libuuid_la-randutils.o): In function `random_get_bytes':
  randutils.c:(.text+0x204): undefined reference to `libintl_gettext'

Add LIBS=-lintl to configure options in case we're building with
standalone gettext.
Fixes:
