- use --enable-default-pie
- patch bind now, ssp-strong, fortify and as-needed to be defaults
- remove gentoo esp patches as unneeded (deprecated by the above)
- update ecj
- remove upstreamed musl patches, add current musl patches
- support musl's static pie
- fix some bootstrapping related issues

-Apply Alpine Linux specific differences to Gentoo ESP configuration:
-- default PIE and SSP by default without additional CFLAGS (to clean up APKBUILD)
-- do not enable -fstack-check by default (caused failures in programs that setup
-  small stack in musl)
-- enable -z relro by default
-- enable -fstack-protector-strong instead of -fstack-protector-all by default
