Bash doesn't have '--disable-shared'.  I used these commands:

# export LDFLAGS=-static
# ./configure --without-bash-malloc \
              --disable-readline \
              --disable-history \
              --disable-help-builtin \
              --disable-progcomp \
              --disable-net-redirections \
              --disable-nls

There were some errors during 'make':

./builtins/libbuiltins.a(enable.o): In function `dyn_load_builtin':
/home/bash/bash-4.2/builtins/./enable.def:307: warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

/home/bash/bash-4.2/shell.c:1657: warning: Using 'endpwent' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

I installed Bash and replaced '/bin/sh'.

Then I adjusted '/usr/local/etc/nix/nix.conf':

build-users-group = nixbld
build-use-chroot = true
build-chroot-dirs = /dev /proc /bin

And ran the following command:

# ./pre-inst-env guix-build -K                \
      -e '(@ (gnu packages make-bootstrap) %bootstrap-tarballs)'  \
      --system=mips64el-linux

Unfortunately, it failed:

I guess that I should adjust the recipe like this:

(setenv "ARCH"
		(cond ((string=? arch "i686")     "i386")
			  ((string=? arch "mips64el") "mips")
			  (else arch)))

(There is 'linux-3.3.8/arch/mips/Makefile'.)

Will this work?

By the way, my local repo is a bit outdated.  Should I update it?
