We want to ensure all packages follow the same coding style, so we add a
blurb about the order of kconfig options' attributes:
- first, the type and the prompt
- the default value if needed
- then dependencies of the 'depends on' category
- followed by dependencies of the 'select' form
- with eventually the help text

Some host packages need a recent gcc version. Add symbols to Config.in
to specify the HOSTCC version. The values are passed through the
environment, and this environment is generated in a new support script.
Also update the documentation to mention the new symbols.

Currently, we forcibly override BR2_EXTERNAL when building the manual,
so as to avoid referring to packages therein from the manual.
However, when generating the lists of packages, we limit ourselves to
scanning for packages in (Buildroot's) TOPDIR and never search in
BR2_EXTERNAL. So, we do not really need to override BR2_EXTERNAL when
generating the manual to achieve the same result.
Furthermore, we're only looking for packages that are defined in the
sub-menu "Target packages", and never anywhere else, and especially not
in the sub-menu "User-provided options".
Finally, we're soon to completely eliminate use of BR2_EXTERNAL in
Kconfig altogether, so that would no longer have any impact anyway.
So, just leave BR2_EXTERNAL alone when generating the manual.

Currently, packages that need to exclude parts of the archives when

When building in a different output directory than the original build,
there will currently be a lot of ccache misses because in many cases
there is some -I/... absolute path in the compilation. Ccache has an
option CCACHE_BASEDIR to substitute absolute paths with relative paths,
so they wil be the same in the hash (and in the output).
Since there are some disadvantages to this path rewriting, it is made
optional as BR2_CCACHE_USE_BASEDIR. It defaults to y because the
usefulness of ccache is severely reduced without this option.
In addition to CCACHE_BASEDIR, we also substitute away the occurences
of $(HOST_DIR) in the calculation of the compiler hash. This is done
regardless of the setting of BR2_CCACHE_USE_BASEDIR because it's
quite harmless.

Because of a limitation in how makedevs resolves names [0], usernames
and groupnames would be resolved with UIDs and GIDs from the host, not
the target.
Fixing makedevs would involve us rewriting a /etc/passwd and /etc/group
parser (not too complex, still not trivial).
Document that the user and group fields should only be numbers, not
names. Also, the manual is currently misleading, as an example indeed
uses names for the user and group fields. Fix that and expand the
explanations.
The mode field should also be numbers, not a rwx combo.
Slight typographical eye-candy about major/minor fields.
[0] it uses getpwnma(3) and getgrnam(3) to resolve names to IDs, and
those only resolve names on the host (i.e. there is no way to specify
a chroot-like feature)

The following allows a user definition to specify that a created user
entry should not have a password value set. Original implementation
allowed a user definition to provide a password value of "=" (no quotes)
to generate a crypt-encoded empty string value. In some cases, it may be
desired to have no value specified for a user's password. By using a
value "-" for a password, no value will be set in the shadow value.
An example when this can be used is when logging into a terminal.
Logging into a session with an encoded empty password will prompt a user
to enter a password since it does not know the password is empty. If the
password field blank, a login session will not prompt for a password.

Commit 53903a15 (*config: improve handling of BR2_LEGACY) added an
option to entirely skip legacy entries, by passing a variable in the
environment.
However, it missed one location where that variable is also needed,
which is generating the list of packages and deprecated features for
inclusion in the manual.
Fix that by re-using the global $(COMMON_CONFIG_ENV) variable,
overriding just what we don't want (i.e. br2-external location and
defconfig path).
Also, slightly re-order variables so the ones we override come right
after the common settings, moving the specific ones at the end, one
variable per line.
