build: Check that -lzstd can be linked
Recent Solaris 11.4 SRUs bundle zstd, but only the 64-bit libraries (no
idea why). Because of this, in 32-bit builds cc1 etc. fail to link with
undefined references to various ZSTD_* functions from lto-compress.o.
This happens because currently only the presence of <zstd.h> is
necessary to enable zstd support in lto-compress.cc etc.
This patch checks for libzstd first and disables zstd support if
missing.
Tested on sparc-sun-solaris2.11 with the system installation of zstd
(64-bit only) and a locally-compiled one (specified with --with-zstd).

gcc:
* configure.ac (ZSTD_LIB): Move before zstd.h check.
Unset gcc_cv_header_zstd_h without libzstd.
* configure: Regenerate.
