27 # Upstream rustc still assumes that musl = static[1]. The fix for
28 # this is to disable crt-static by default for non-static musl
29 # targets.
30 #
31 # For every package apart from Cargo, we can fix this by just
32 # patching rustc to not have crt-static by default. But Cargo is
33 # built with the upstream bootstrap binary for rustc, which we can't
34 # easily patch. This means we need to find another way to make sure
35 # crt-static is not used during the build of pkgsMusl.cargo.
36 #
37 # By default, Cargo doesn't apply RUSTFLAGS when building build.rs
38 # if --target is passed, so the only good way to set -crt-static for
39 # build.rs files used in the Cargo build is to use the unstable
40 # -Zhost-config Cargo feature. This allows us to specify flags that
41 # should be passed to rustc when building for the build platform.
42 # We also need to use -Ztarget-applies-to-host, because using
43 # -Zhost-config requires it.
44 #
45 # When doing this, we also have to specify the linker, or cargo
46 # won't pass a -C linker= argument to rustc. This will make rustc
47 # try to use its default value of "cc", which won't be available
48 # when cross-compiling.
