Bootloader fork rebase:
- Base changed from 0.1.0 pre-patched archive to upstream 1.0.0 tag (c7eeb9f)
- Applied 0001-redbear-local-forks.patch (Cargo.toml crate path redirects)
- Applied fix-uefi-alloc-panic.patch equivalents (4 panic!() -> graceful
error handling in src/main.rs)
- Applied P5-live-preload-cap-1gib.patch (1 GiB cap on live image preload)
- Skipped: P0 GPT partition scan (requires new module + integration),
P1 timeout/default-resolution, P2 live preload guard (subsumed by
panic fixes + cap), P3 live image safe read, P4 large ISO boot,
redox.patch — to be applied in dedicated rebase session.
firmware-loader/Cargo.toml: version 0.1.0 -> 0.3.0 (sync with other
Red Bear custom crates which are at 0.3.0).
fork-upstream-map.toml: bootloader back from PENDING_REBASE to 1.0.0
since the partial rebase matches upstream 1.0.0 content.
fork-upstream-map.toml: base restored to 'main' tracked (was correctly
tracked by build-redbear.sh).

# Determine whether the compiler is or may be producing universal binaries.
|
|
#
|
|
# On Mac OS X 10.5 and later systems, the user can create libraries and
|
|
# executables that work on multiple system types--known as "fat" or
|
|
# "universal" binaries--by specifying multiple '-arch' options to the
|
|
# compiler but only a single '-arch' option to the preprocessor. Like
|
|
# this:
|
|
#
|
|
# ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
|
# CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
|
# CPP="gcc -E" CXXCPP="g++ -E"
|
|
#
|
|
# Detect this situation and set APPLE_UNIVERSAL_BUILD accordingly.
