# AArch64 Linux musl targets are repeatedly affected under varying

# circumstances by fixedn't linking issues to compiler builtin symbols.

# Linking to libgcc, though arguably an inelegant hack that's only portable
|
|
# to our glibc from musl crosscompilation scenario, is effective to reliably
|
|
# provide an implementation of those fundamental symbols over time, without
|
|
# user-visible impacts on the final executables. See:
