Many Linux build systems (autoconf, distutils, setuptools, pip build backends, scikit-build, etc.) probe for the architecture-prefixed binary names — `x86_64-linux-gnu-gcc`, `aarch64-linux-gnu-g++`, etc. — before falling back to plain `gcc`. Without these symlinks, pip-install of any Python C-extension wheel fails on Ubuntu/Debian rootfs even when `gcc` IS on PATH. Addresses one of the two complaints in pkgxdev#8423. The other issue raised there (`stdlib.h: No such file or directory` on Fedora) is the libc-headers gap — pkgx's gcc relies on the system glibc-devel for /usr/include/stdlib.h etc. That requires a separate gnu.org/glibc bottle + runtime dep wiring; see bklibcvenv-pattern follow-ups (pkgxdev#12968 and brewkit#348).

Summary
Why
Many Linux build systems probe for the architecture-prefixed binary names (`$ARCH-linux-gnu-gcc`) before falling back to plain `gcc`:
Without these, `pkgx install gcc` works on Fedora-style rootfs but fails on Ubuntu/Debian-style rootfs even though gcc IS on PATH.
Addresses the first of two issues raised in #8423.
Out of scope
The second issue in #8423 — `stdlib.h: No such file or directory` on Fedora — is the libc-headers gap. pkgx's gcc relies on the system glibc-devel for /usr/include/. That requires a separate `gnu.org/glibc` bottle + runtime dep wiring; see the bklibcvenv-pattern follow-ups (#12968 and brewkit#348).
