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.

Linaro toolchain for the ARM big endian architecture. It
|
|
uses Linaro GCC 2018.05 (based on gcc 7.3.1), Linaro GDB
|
|
2018.05 (based on GDB 8.1), glibc 2.25, Binutils 2018.05
|
|
(based on 2.28). It generates code that runs on all Cortex-A
|
|
profile devices, but tuned for the Cortex-A9. The code
|
|
generated is Thumb 2, with the hard floating point calling
|
|
convention, and uses the VFPv3-D16 FPU instructions.
