This patch resolves clipped LD_LIBRARY_PATH. Using hugectl to enable use of
hugepage for an application on a system with SLES11 SP1. hugectl was clipping
my LD_LIBRARY_PATH at 254 characters and preventing execution. NAME_MAX on my
platform is 255. This patch allows LD_LIBRARY_PATH to be up to 4096 characters
on my platform.

Eric,
I was using hugectl to enable use of hugepage for an application on a system
with SLES11 SP1. hugectl was clipping my LD_LIBRARY_PATH at 254 characters and
preventing execution. NAME_MAX on my platform is 255. This patch allows
LD_LIBRARY_PATH to be up to 4096 characters on my platform.

Dan,
I can't take this patch without a leader that has a Signed-off-by, at
the very least. It should also do a little to explain the problem your
are correcting.
Thanks,
Eric
