1539533c54Binary-specific link flags (-nostartfiles, -static, section stripping) now use cargo:rustc-link-arg-bin so they don't break proc-macro or build-script linking. ld-wrapper only strips sections from static binaries.

# Use a linker wrapper that invokes mold then strips junk sections with objcopy.

# mold cannot discard .eh_frame/.dynstr/.comment via linker scripts, so we do
|
|
# it as a post-link step.

# See:

# Binary-specific link flags live in microfetch/build.rs via cargo:rustc-link-arg-bin
|
|
# so they only affect the final binary and don't break proc-macro or build-script linking.
