[bug#70065] [PATCH v2 4/8] gnu: chez-scheme: Update to 10.0.0.

[Philip McGrath <philip@philipmcgrath.com>]

* gnu/packages/patches/chez-scheme-bin-sh.patch: Refresh patch.
* gnu/packages/patches/chez-scheme-backport-configure.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/chez.scm (chez-scheme): Update to 10.0.0.  Inherit from
'chez-scheme-for-racket'.
[source]<patches>: Use "chez-scheme-backport-configure.patch".
<snippet>: Also unbundle Zuo.
[native-inputs, native-search-paths, outputs, arguments]
[supported-systems]: Inherit from 'chez-scheme-for-racket'.
[inputs]: Likewise, replacing the bootfile package and adding libx11.
[description]: Update based on the User's Guide, release notes, man
page, and README file.
(chez-scheme-bootstrap-bootfiles)[supported-systems]: All systems are
now supported.
(chez-scheme-for-system): Return 'chez-scheme', since it now supports
all systems.

+Subject: [PATCH 1/2] Repairs and improvements for building with external
+ dependencies (#807)
+
+* configure: fix zlib and lz4 submodule checks
+
+Conditionals to skip the submodule checks were using the wrong
+variable names, so the checks were always skipped. The correct
+behavior is to perform the check unless given `ZLIB=<zlib>` or
+`LZ4=<lz4>`, as applicable.
+
+* configure: support `ZUO=<zuo>`
+
+Supplying `ZUO=<zuo>` skips the submodule check in `configure`
+and configures the generated makefile not to build or remove Zuo.
+
+* configure: support `STEXLIB=<stex>`
+
+For compatibility with older scripts, when not explicitly configured,
+continue to honor the `STEXLIB` environment variable at build time.
+

+Subject: [PATCH 2/2] adjust `configure ZUO=<command>` support (#816)
+
+Continuing from b8838c3280, adjust the generated makefile so the
+supplied `<command>` is not a makefile dependency. That way, `ZUO=zuo`
+works if `zuo` is installed and the current build directory is not the
+source directory. (The `zuo` executable is a dependency in a real and
+relevant sense, but not in the sense of dependencies that we normally
+track in makefiles.)
+
+Also adapt the makefile for the case that `ZUO=...` is not supplied
+and the build directory is not the source directory, in which case
+`ZUO_LIB_PATH` needs to be relative to the source directory.
+
+Using `make ZUO=zuo` can also work, but in that case, `bin/zuo` is
+still built as a dependency. It's possible that some portable makefile
+magic could overcome that limitation, but it doesn't seem important.
+
+(cherry picked from commit d327968f37cdf669d15a9ad6d356bbf92c502bb9)
