Also don't bootstrap it in bootstrap.sh. Since we no longer use the grsecurity patchset (which also provides PaX) and paxmark was recently removed from all remaining packages, there should be no need to bootstrap it early or include it in the images.

This script creates a local cross-compiler, and uses it to
|
|
cross-compile an Alpine Linux base system for new architecture.
|
|
|
|
Steps for introducing new architecture include:
|
|
- adding the compiler triplet and arch type to abuild
|
|
- adding the arch type detection to apk-tools
|
|
- adjusting build rules for packages that are arch aware:
|
|
gcc, openssl, linux-headers
|
|
- create new kernel config for linux-lts
|
|
|
|
After these steps the initial cross-build can be completed
|
|
by running this with the target arch as parameter, e.g.:
|
|
./$program aarch64
|
|
