When Bash attempts to find the current working directory, it uses a C
library call `getcwd` to resolve it. When cross-compiling, the
configuration process cannot determine if the target system's C library
can support an "unfixed" path length. Therefore, Bash will fallback to a
size of `PATH_MAX` for determining the current working directory. When
using OverlayFS (and possible other file systems), this becomes an issue
since file paths can commonly exceed standard `PATH_MAX` length. This
typically results in the following error appearing:
error retrieving current directory: [...]
Common C library `getcwd` calls can default to a higher limit (usually
the system's page size). The current configurable C libraries (as of at
least 2015.08) support a zero (0) size buffer length. Most use the
system's page size; musl, being an exception, which defaults to
`PATH_MAX` (as Bash was doing). Since these C libraries support
allocating buffer space with a zero (0) provided size, the following
configuration change allows Bash to support getting a larger-length'ed
working directory on target's that support it.

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

bash fails to link for static builds with uClibc toolchains due to
getenv redefinitions. This is caused because bash is unable to check if
getenv is already defined when cross-compiling, so it defaults to 'yes':
configure:14438: WARNING: cannot check getenv redefinition if cross
compiling -- defaulting to yes
We can avoid this redefinition by passing bash_cv_getenv_redef=no to the
configure script.

Not all our shells do install a pointer to /bin/sh. Besides, between
those that do and multiple ones are enabled, the last one to install
wins the the symlink.
Add a new config choice in the system sub-menu that allows the user to
explicitly select the shell to provide /bin/sh. If busybox is not
enabled, default to using dash, a POSIX shell.
Remove the symlink creation from bash.mk at the same time.
Note: for every shell, we select them, except busybox, on which we
depend, on the assumption that we do not want to force busybox in case
the user decided not to enable it.

Patch bash32-011 modifies the configure.in script. Therefor we need to
run autoconf before launching the configure script. Otherwise, once
the configure script called, the makefile's dependencies over
configure.in will relaunch autoconf without options/environnement
variables we usually set when calling configure.

-Force some autoconf options so that job control
is turned on.
(Otherwise these checks fail when cross compiling.
And when job control is disabled, bash can't be
the default shell)
they should be configured with --prefix=/usr and we then need to use
make DESTDIR=$(STAGING_DIR) install to get things installed into the
staging directory. The current situation for many packages, which use
--prefix=$(STAGING_DIR) results in the staging_dir paths getting compiled
into the binary itself.
This also adds in a pile of libtool fixups. Between broken pkgconfig,
broken libtool handling, and broken --prefix settings, its a wonder
things have worked as well as they have up till now.
