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). Ok for trunk?
OK jeff
