# Honour the build script's own linking directives, which buck2 drops by
# default. It compiles aws-lc's C into `libaws_lc_0_43_0_crypto.a` in OUT_DIR
# and emits `cargo:rustc-link-lib` and `cargo:rustc-link-search` to have it
# linked; without these two the flags file came out as `--cfg=universal` alone
# and the archive sat on disk unreferenced, leaving 129 `aws_lc_0_43_0_*`
# symbols undefined in every buck2-built libjoltmoq.so.
#
# Nothing caught that for as long as nothing loaded one. Undefined symbols are
# legal in a cdylib, and `--no-undefined` was only ever on libjoltapp's own
# link, which is a different object. The phone is the first consumer to dlopen
# it, and there it fails outright on `aws_lc_0_43_0_EVP_PKEY_free`.
