Copy Alpine's gcc6 aport to temp. They don't have it built for aarch64 and armhf at the moment. Due to dependency checks, this means we can't build the kernels that need gcc6, even when cross compiling with gcc6-armhf etc. See #138 for details.

Alpine musl package provides libssp_nonshared.a. We link to it unconditionally,
|
|
as otherwise we get link failures if some objects are -fstack-protector built
|
|
and final link happens with -fno-stack-protector. This seems to be the common
|
|
case when bootstrapping gcc, the piepatches do not seem to fully fix the
|
|
crosstoolchain and bootstrap sequence wrt. stack-protector flag usage.
