Building Sed bzlmod with gcc-toolchain fails for nl_langinfo.c symbols 'ALTMON_*' #212
Description
I am trying to build the Sed bazel module via Bazel 7 & 8 and gcc-toolchain v0.9.0 on an Ubuntu 24.04 host. With the toolchain active the build fails. Without using the gcc-toolchain it succeeds.
Errors seen:
$ bazel build @sed//:sed

I have tried naively using --copt=-D_GNU_SOURCE with no luck.
Is this issue expected or is there a workaround? Thank you.
