Replace *MD5SUM with *HASH, replace MD5 hashes with SHA256 Signed-off-by: Felix Fietkau

toolchain: Rework external toolchain libc selection

2016-09-28T06:39:01Z

Make it a choice menu which offers the 3 C libraries we know about: glibc, uClibc and musl. While at it, make it possible for the external toolchain libc to select USE_GLIBC, USE_UCLIBC or USE_MUSL which is used by several packages to conditionally include specific CFLAGS (e.g: iproute2). Because USE_GLIBC et al. can now be selected by external toolchains, we need to restrict the per-libc menus to check on !EXTERNAL_TOOLCHAIN. While at it, make musl the default C library for external toolchain to match the internal toolchain. Signed-off-by: Florian Fainelli Signed-off-by: Felix Fietkau

glibc: add 2.24

2016-08-30T08:51:21Z

toolchain: skip gcc/minimal for musl

2016-07-07T13:13:40Z

No extra libc header build step is done, so no extra toolchain is needed for preparing it. This saves a significant amount of build time and disk space Signed-off-by: Felix Fietkau
