gcc/ChangeLog:
* doc/install.texi: Document the configure option --with-zstd.
default is derived from glibc's behavior. When glibc clamps float_t to double,
GCC follows and enables the option. For other cross compiles, the default is
disabled.
+
+@item --with-zstd
+Specify prefix directory for installed zstd library.
+Equivalent to @option{--with-zstd-include=PATH/include} plus
+@option{--with-zstd-lib=PATH/lib}.
