xbps-src: move compiler/linker defaults to env/hardening.sh. The user can still set his/her defaults via etc/conf, and per package in the templates.

# Enable SSP and FORITFY_SOURCE=2 by default.
env/hardening: fix hardening on MIPS. Thanks to @chneukirchen for finding the correct solution: gcc sets -mno-shared by default when compiling non-PIC, and because we are overriding the builtin specs, this internal rule set for gnu/mips does not trigger: gcc/config/mips/gnu-user.h:/* Default to -mno-shared for non-PIC. */ gcc/config/mips/gnu-user.h: " %{mshared|mno-shared|fpic|fPIC|fpie|fPIE:;:-mno-shared}" So that we now use a specific specs file just for mips that sets -mshared for PIC. This fixes building packages with hardening enabled for MIPS.

env/hardening: reenable hardening for MIPS. I just booted a full PIE base-system successfully on my CI20 Creator. For now we set -fPIE again in C{,XX}FLAGS to fix the build in attr/acl/coreutils, etc.
