We call this "zig-build" instead of just "zig" as this build-style
relies on usage of the zig build system. In the future, other build
systems such as meson may support zig code. Furthermore, the zig
build system may be used to build C/C++ code as well, not just zig.
Provide new environment variables for simplifaction of template checks:
...ENDIAN defines the (target) machine's endianness: "le" or "be".
...LIBC defines the (target) machine's C library: "glibc" or "musl".

This still isn't perfect. When the common/xbps-src/shutils/chroot.sh
function chroot_init() is called, the value for $XBPS_FFLAGS, which is
defined in common/build-profiles/bootstrap.sh, is empty.
Put the immediate value into the generated /etc/xbps/xbps-src.conf
file until someone finds out where passing the value of $XBPS_FFLAGS
throughout the scripts is missing.
Rather than setting them in the build profile, just set them in
etc/defaults.conf (overridable via etc/conf) to simplify the code.
- Also enable _FORTIFY_SOURCE=2 in CPPFLAGS.
- Also enable -z,relro in LDFLAGS.
As suggested by @chneukirchen.
common/build-profiles contains the compilation flags used in native
builds, and are defined per architecture:
- x86_64 (glibc)
- x86_64-musl (musl)
If XBPS_CFLAGS or XBPS_CXXFLAGS are set in `etc/conf`, the settings
from the build profile will be overrided.
