binutils

• Does not allow autoreconf and does not have runstatedir
• Depends on zstd
• Do we need to depend on jansson with --enable-jansson, or is that for gdb only?
• Alpine reverts 25882 for ARM and PowerPC
• --disable-separate-code bloats every executable and shared library by at least 2 MB; musl-cross-make weirdly uses this
• --enable-64-bit-bfd is needed to ensure 64-bit support even on hosts with narrower word sizes
• Is libbfd even needed --disable-install-libbfd (same thing for libiberty, --disable-install-libiberty)?
• --enable-pgo-build=lto requires dejagnu and the test suite?
• Do we need make configure-host configure-target?
• Should the target bpf-unknown-none be enabled?
• Does --enable-default-compressed-debug-sections-algorithm=zstd contradict with --disable-compressed-debug-sections and enables compressed debug sections, or does it only set the default algorithm if the user decides to use compressed debug sections?
• --with-build-sysroot is only relevant in cross
• Do not symlink toolchain/usr/$TGT to gcc-ar/gcc-nm/gcc-ranlib as it will loop infinitely and thrash your system
• bfd does not build with yash; only with dash and bash
• gold has been deprecated
