Compiling with musl?

Hi there, with a up-to-date `stable` and `x86-86-unknown-linux-musl` target, I seem unable to compile this library (as a dependency of `curl` and `isahc`). With:
```
cargo build --release --target x86_64-unknown-linux-musl
```
I get many messages of the form:
```
cargo:warning=In file included from /usr/include/bits/endian.h:35,
cargo:warning= from /usr/include/endian.h:24,
cargo:warning= from /usr/include/sys/types.h:176,

cargo:warning=/usr/include/bits/endianness.h:9: warning: "__BYTE_ORDER" redefined
cargo:warning= 9 | #define __BYTE_ORDER __LITTLE_ENDIAN
cargo:warning= |
```
Followed by a complaint about `musl-gcc` exiting with an error code. I have the latest `curl` system packages installed on my machine, so I'm not sure what the issue is. Any thoughts? Thank you.
