I realized the glibc static build does actually work (though prints
warnings at compile time), so I made it no longer hard-coded to the
compiler. It's still a bad idea, so I added notes for why you shouldn't
do it with glibc.
The `x86_64-unknown-linux-musl` target does not build dynamic libraries
for now:
```
warning: dropping unsupported crate type `cdylib` for target `x86_64-unknown-linux-musl`
```
A target may now be optionally specified to the root `Makefile`,
example:
`make RUST_TARGET=x86_64-unknown-linux-musl && sudo make
RUST_TARGET=x86_64-unknown-linux-musl install`
The new musl targets may be used to create entirely static binaries with
libextism. See the new `musl-static` target in `libextism/Makefile`
Adds `pkg-config` configs for dynamic and static builds of libextism.
Example usage is shown in `libextism/Makefile`.
Added the `.in` versions of the `.pc` files to non-MSVC releases.
See #504
Removes CI for the in-repo SDKs, we can remove the actual code closer to
the 1.0 release.
