[Patch] Reenable LD_PATHS, as suggested by Makefile.leaf

[Nick Withers]

Hey there!

Here's a patch to re-enable LD_PATHS (I have an external library,
RTEMS_gdb_stub, to pull in) in gcc-target-default.cfg:
____

diff --git a/c/src/make/compilers/gcc-target-default.cfg

(I've added an extra space after "LDFLAGS+=" since I emailed this in
http://www.rtems.org/pipermail/rtems-devel/2013-July/003497.html )

See
http://git.rtems.org/rtems/commit/c/src/make/compilers/gcc-target-default.cfg?id=ea9f76742163cccf98eb326db7459c18d2fad1b6 for why LD_PATHS had been commented ("Now implicitly handled by gcc-spec").

Makefile.leaf suggests that this variable should be used, so I think
putting it back is the right thing to do...?
