# Upstream rustc still assumes that musl = static[1]. The fix for
|
|
|
|
|
# this is to disable crt-static by default for non-static musl
|
|
|
|
|
# targets.
|
|
|
|
|
#
|
|
|
|
|
# Even though Cargo will build build.rs files for the build platform,
|
|
|
|
|
# cross-compiling _from_ musl appears to work fine, so we only need
|
|
|
|
|
# to do this when rustc's target platform is dynamically linked musl.

# applied to the target. It's fine to do this for -crt-static,
