James Hilliard 3b3105328e Config.in: only allow BR2_STATIC_LIBS on supported libc/arch
It is currently possible to select BR2_STATIC_LIBS while
BR2_TOOLCHAIN_BUILDROOT is selected even when there are no buildroot
toolchains that support BR2_STATIC_LIBS for the selected architecture.

Add BR2_TOOLCHAIN_BUILDROOT_STATIC_LIBS_SUPPORTS so that we can
disable the selection of BR2_STATIC_LIBS when using an unsupported
architecture.

string "custom toolchain vendor name"
default "buildroot"
help
This option allows to customize the "vendor" part of the
toolchain tuple, where the toolchain tuple has the form
<arch>-<vendor>-<os>-<libc>. The default value, "buildroot",
is fine for most cases, except in very specific situations
where gcc might make different decisions based on the vendor
part of the tuple. The value "unknown" is not allowed, as the
cross-compiling toolchain might then be confused with the
native toolchain when the target and host architecture are
identical. The value can not be empty either.
If you're not sure, just leave the default "buildroot" value.
