Currently, glibc depends on !BR2_STATIC_LIBS in all the toolchain variants. However, for some architectures, glibc is the only supported libc. In commit3b3105328e("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 commit3b3105328eprevents 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.

Say 'y' here if you plan on running your system on a kernel
|

older than the version used for the toolchain headers.
|
|
|

Enabling those compatibility shims may generate a slightly
|
|
bigger and slightly slower glibc library.
|

The oldest supported kernel version depends on the

architecture.
