lightning: add -lintl only when needed

Browse Source 
Adding -lintl to LIBS causes a failure in the configure phase when using
a toolchain which already has locale support because the intl library is
not present in the staging area. We fix this by adding -lintl only when
is needed.

This is the configure error:

checking whether the C compiler works... no
configure: error: in
`/br/output/build/lightning-2.0.5':
configure: error: C compiler cannot create executables
See `config.log' for more details

This is the message in the config.log:

configure:3351: /br/output/host/usr/bin/mips-linux-gnu-gcc
-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os
-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64
conftest.c -lintl >&5
/br/output/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/4.9.1/../../../../mips-linux-gnu/bin/ld:
cannot find -lintl

[Thomas:
 - Adjust the fix to not add a dependency on gettext: lightning
   doesn't depend on gettext. It is just that binutils libraries are
   linked against libintl when available, and we need to add -lintl
   explicitly in such cases.]
