gnu: ghc@4: Replace config.sub using config package.

* gnu/packages/haskell.scm (ghc@4)[arguments]: Adjust custom 'bootstrap
phase to adjust replacement of config.sub.
[native-inputs]: Remove automake, add config.

powerpc64le-linux and riscv64-linux.
[arguments]: Set #:system to the 32-bit version of our supported 64-bit
architectures. Modify custom 'set-dynamic-linker-file-name phase to use
the glibc-dynamic-linker for the selected system, and to substitute more
locations.

* gnu/packages/python-xyz.scm (python-mt-940): New variable.

gnu: trash-cli: Use pytest for testing.

Running setup.py overwrites the wrappers created by the 'wrap phase.

Fixes: <https://issues.guix.gnu.org/53695>

* gnu/packages/shellutils.scm (trash-cli)[arguments]: Replace 'check
phase with call to pytest.

doc: Move build commands to @example for clarity.

* doc/contributing.texi (Building from Git): Tweak so that all the
commands appear in @example boxes.  Show --localstatedir=/var instead of
--localstatedir=@var{directory}.

doc: Clarify the Swap Space examples, and include an helper example.

* doc/guix.texi (Swap Space): The examples referred to variables
defined outside of the snippets, and so were not very informative for
people without much Guile knowledge.  Instead, refer to mapped-devices
for the first, and use the new helper
file-systme-mount-point-predicate for the second.

Signed-off-by: Ludovic Courtès <ludo@gnu.org>

system: Add helper file-system-mount-point-predicate.

* gnu/system/file-systems.scm (file-system-mount-point-predicate): Add
it.

gexp: 'computed-file' always uses a native Guile.

Fixes a regression whereby, when cross-compiling, 'computed-file' would
use a cross-compiled Guile as its builder, which would fail to run.

Regression introduced in af57d1bf6c46f47d82dbc234dde1e16fa8634e9d (the
problem had always been there but was hidden before behind the (not guile)
condition.)

* guix/gexp.scm (computed-file-compiler): For 'guile', pass #:target #f.
* tests/gexp.scm ("lower-object, computed-file, #:target"): New test.
