Because there's no package like x86_64-linux-gnu-glibc in Arch Linux's repo,
we must bootstrap from scratch.

Build Order

Target linux api headers and binutils:

x86_64-linux-gnu-binutils(addpkg: x86_64-linux-gnu-binutils 2.43-1 #4342)
x86_64-linux-gnu-linux-api-headers(addpkg: x86_64-linux-gnu-linux-api-headers 6.12-1 #4343)

Build bare gcc to compile glibc stubs:

x86_64-linux-gnu-gcc-bootstrap(addpkg: x86_64-linux-gnu-gcc-bootstrap 14.2.0-1 #4348)

Build glibc stubs with x86_64-linux-gnu-gcc-bootstrap

x86_64-linux-gnu-glibc-headers(addpkg: x86_64-linux-gnu-glibc-headers 2.40-1 #4349)

Build a minimal gcc with x86_64-linux-gnu-glibc-headers

x86_64-linux-gnu-gcc(addpkg: x86_64-linux-gnu-gcc 14.2.0-1 #4350)

Build full target glibc with the minimal gcc:

x86_64-linux-gnu-glibc(addpkg: x86_64-linux-gnu-glibc 2.40-1 #4351)

Build full gcc now:

x86_64-linux-gnu-gcc (updpkg: x86_64-linux-gnu-gcc 14.2.0-2 #4356)

Optionally build target glibc again with full gcc and then rebuild gcc:

x86_64-linux-gnu-glibc
x86_64-linux-gnu-gcc
