Arnout Vandecappelle (Essensium/Mind) 90932b407c toolchain: invert glibc <-> !static dependency 
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]
