# FIXME(sparc): newer versions of Ubuntu get the following errors
# ```
# /prog: /lib/sparc64-linux-gnu/libm.so.6: version `GLIBC_2.38' not found (required by /prog)
# /prog: /lib/sparc64-linux-gnu/libc.so.6: version `GLIBC_2.39' not found (required by /prog)
# ```
# Not sure if this is a problem from rustc, our libc, or Ubuntu so we just
# stick with an old LTS for now.
