I just did this (together with the paramater "-K"!), but the problem is
that I have no idea what is happening inside...

The configure phase actually passes, the problem appears inside the build
phase, which itself launches a number of configure runs in subdirectories.
The last lines of the log are:
checking size of void *... 4

I launched a ./configure by hand inside the ld subdirectory, after sourcing
the environment variables; it succeeds with
checking size of void *... 4
configure: creating ./config.status
config.status: creating Makefile
config.status: creating po/Makefile.in
config.status: creating config.h
config.status: config.h is unchanged
config.status: executing depfiles commands
config.status: executing libtool commands
config.status: executing default-1 commands
config.status: creating po/POTFILES
config.status: creating po/Makefile

So even during the build, configure runs until the last test.
However, it does not write ./config.status etc.

The error message above contains
make[1]: *** [Makefile:7125: configure-ld] Error 1

Lines 7125 and following of the Makefile (one level up from the ld
subdirectory) are
configure-ld:
        @r=`${PWD_COMMAND}`; export r; \
        s=`cd $(srcdir); ${PWD_COMMAND}`; export s; \
        test ! -f $(HOST_SUBDIR)/ld/Makefile || exit 0; \
        $(SHELL) $(srcdir)/mkinstalldirs $(HOST_SUBDIR)/ld; \
        $(HOST_EXPORTS)  \
        echo Configuring in $(HOST_SUBDIR)/ld; \
        cd "$(HOST_SUBDIR)/ld" || exit 1; \
        case $(srcdir) in \
          /* | [A-Za-z]:[\\/]*) topdir=$(srcdir) ;; \
          *) topdir=`echo $(HOST_SUBDIR)/ld/ | \
                sed -e 's,\./,,g' -e 's,[^/]*/,../,g' `$(srcdir) ;; \
        esac; \
        module_srcdir=ld; \
        $(SHELL) \
          $$s/$$module_srcdir/configure \
          --srcdir=$${topdir}/$$module_srcdir \
          $(HOST_CONFIGARGS) --build=${build_alias} --host=${host_alias} \
          --target=${target_alias}  \
          || exit 1

So apparently the "exit 1" is triggered.
The beginning of the configure log looks like this:
Configuring in ./ld
configure: creating cache ./config.cache
checking build system type... mips64el-unknown-linux-gnu
checking host system type... mips64el-unknown-linux-gnu
checking target system type... mips64el-guix-linux-gnu
So it looks as if build_alias, host_alias and target_alias are set
correctly.

Do you have any ideas of what to check?
