Make it possible to build old kernels with gcc4 for armv7 and aarch64. The packages have been generated with (as usually): $ pmbootstrap aportgen gcc4-aarch64 gcc4-armv7 [ci:skip-build]: I have tested that this builds locally. Fixes #193.

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.
