[Buildroot] [PATCH 7/8] libssh2: fix static link with libgcrypt

[Jérôme Pouiller]

BR call configure script with environment variable
lt_cv_sys_lib_search_path_spec="" (see packages/Makefile.in). This prevent
libtool to detect compiler builtin paths. Thus, in case where
BR2_PREFER_STATIC_LIB is enabled, libtool does not find libgpg-error
dependency:

/home/jezz/br-continuous/cfgs/31-x86_64-core2-uclibc-static/host/usr/i686-buildroot-linux-uclibc/sysroot/usr/lib/libgcrypt.a(rsa.o):
In function `run_selftests':
rsa.c:(.text+0xd2): undefined reference to `gpg_strerror'
rsa.c:(.text+0xfc): undefined reference to `gpg_strerror'

For this case, we may remove $lt_cv_sys_lib_search_path_spec from environment.
However, it not easy to remove a variable from default environment. So, we
prefer to pass a correct value.
