Apparently big endian glibc builds just work, if we let the endian header allow that (which prev was #error). So this patch bumps glibc to version which fixes the header (this hopefully will become arc-2019.09-release) and then enables arceb in glibc toolchain builds Signed-off-by: Vineet Gupta <vgupta@synopsys.com> --- package/glibc/glibc.mk | 2 +- toolchain/toolchain-buildroot/Config.in | 3 ++- 2 files changed, 3 insertions(+), 2 deletions(-)
