build-proton-tc.sh: Drop -march=native optimization

Recent benchmarks have shown that -march=native either doesn't change anything or actually introduces a regression in kernel build times using the resulting toolchain. Drop it for improved compatibility and reduced maintenance costs as we only need a single build now. GitHub issue: ClangBuiltLinux#55 (comment) Signed-off-by: Danny Lin <[email protected]>
