Subject: [PATCH] install: fix crash with --strip and large $PATH on ppc and
 sparc

* gnulib: Update to the latest gnulib to pull in the fix
(v1.0-2406-g89f63027de) to allocate the $PATH processing memory
before the vfork call, which is required on ppc and sparc.
* tests/install/basic-1.sh: Ensure posix_spawnp() suports a large $PATH,
which needs careful handling with vfork() as detailed in gnulib.
