Here is the error:
set-mode-acl.c: In function 'qset_acl':
set-mode-acl.c:72:6: error: #error Must have acl_delete_def_file (see POSIX 1003.1e draft 17).
This is mainly useful for specifying mounts that depend on other
units. For example sshfs or davfs need network (and possibly
nameservices).
While systemd makes a distinction between local and remote
filesystems, this only works for in-kernel filesystems such as
nfs and cifs.
fuse-based filesystems (such as sshfs and davs) are classified as
local, so they fail without networking. By explicitly declaring these
mounts as full systemd units (as opposed to having systemd generate
them automatically from /etc/fstab), dependencies can be specified as
on every other unit.
In the future, we can probably port NixOS' filesystems handling to use
these native systemd.mount units and skip /etc/fstab altogether, but
this probably requires additional changes, such as starting systemd
even earlier during boot (stage 1).
Without it, gcc builds for softfloat, and the glibc doesn't have support for
softfloat (it ends up requiring some gnu-soft.h file). We'll have to test if
this fixes the build of gcc or not, though.
Although patching it made some programs run (configure tests), some others
crashed with segfault. So I don't think there is any win patching it. The
proper way to solve the bootstrap in the raspberry pi is, as far as I've been
testing, use glibc 2.17 libs in bootstrap-tools with the same ld.so name as the
bootstrapped glibc.
This is a problem inherent in our way to bootstrap, that first replaces
the glibc of a given gcc+glibc (bootstrap-tools) with gcc-wrapper tricks, and
then builds a new gcc. A nicer way would be to build a gcc without glibc,
then the glibc, then the final gcc, as we do with cross-tools.

This solves the problem of the change of name in ld.so between
glibc 2.13 and 2.17 (at least for armhf). Some comments about it in
https://github.com/NixOS/nixpkgs/issues/234#issuecomment-11764352
As there says, without this, gmp (after glibc built) tests crashed
- segfault.
Now that we have a way to alter /bin/sh in chroots on non-NixOS Linux
platforms, it may be useful to have access to stdenv.shell package and to
static bash contained in bootstrap tools. So make them accessible via stdenv
attribute set.
libstdc++ and libmudflapth link to the dynamic loader; if the
bootstrap uses another dynamic loader name, and the rpath of these
libs isn't changed, they will fail to load.
