Previously, it was possible to select an external toolchain that did not
support the GCC arch tuning the user had selected. This is problematic
because it can lead to confusing error messages during builds [0].
Now, external toolchain selections will be filtered to only those that
support the required GCC version specified by the target arch tuning.
Note: this patch does not touch the Bootlin toolchain config file as it
is generated by a script.
Additional note: there is "soft" support for toolchains prior to GCC 4.8
but there are no accompanying BR2_ARCH_NEEDS_GCC_AT_LEAST_X symbols.
Instead of adding those, just use BR2_ARCH_NEEDS_GCC_AT_LEAST_4_8 which
is the minimum GCC version with claimed support [1].

It's time to finally switch over globally to the new spacing format
that we have agreed on for the hash file, with 2 spaces as a separator
between fields.
This commit was mechanically generated using:
find . -type f -name '*.hash' | xargs sed -i 's%^md5[ \t]*\([^ \t]*\)[ \t]*\(.*\)$%md5 \1 \2%'
find . -type f -name '*.hash' | xargs sed -i 's%^sha1[ \t]*\([^ \t]*\)[ \t]*\(.*\)$%sha1 \1 \2%'
find . -type f -name '*.hash' | xargs sed -i 's%^sha256[ \t]*\([^ \t]*\)[ \t]*\(.*\)$%sha256 \1 \2%'
find . -type f -name '*.hash' | xargs sed -i 's%^sha512[ \t]*\([^ \t]*\)[ \t]*\(.*\)$%sha512 \1 \2%'
This commit can easily be backported on the LTS branch by re-running
the same commands, if needed.

Currently, glibc depends on !BR2_STATIC_LIBS in all the toolchain
variants.
However, for some architectures, glibc is the only supported libc. In
commit 3b3105328e ("Config.in: only
allow BR2_STATIC_LIBS on supported libc/arch"), we implemented a fix
to avoid configurations were BR2_STATIC_LIBS=y with an architecture
already supported by glibc, because these configurations are
impossible. This commit 3b3105328e
prevents from selecting BR2_STATIC_LIBS=y when the C library used for
the internal toolchain backend is glibc.
However, it introduces a discrepency between how this topic is handled
for internal and external toolchains:
- For internal toolchains, we prevent BR2_STATIC_LIBS=y if glibc is
chosen.
- For external toolchains, we allow BR2_STATIC_LIBS=y in all cases,
and it's each glibc toolchain that has !BR2_STATIC_LIBS
This commit addresses this discrepency by preventing BR2_STATIC_LIBS=y
if glibc is chosen in all cases.
Thanks to this, we can remove the !BR2_STATIC_LIBS dependency on both
the glibc package, and all glibc external toolchains.

[Thomas: update to master, fix the gen-bootlin-toolchains script, add
a comment in the static/shared choice to indicate that static is
supported only with uclibc or musl]
