Comment:
here are two issues with the current musl package.
For the first issue (build), gcc-final is clobbering the symlink for ld-
musl-*-.so.1 via ldconfig. Essentially, the link is broken on most build
hosts because it uses an absolute path to "/lib/libc.so", so ldconfig just
decides to delete it.
The second issue (kernel panic) is platform specific, probably when
building big endian or hard float variants, as the current gcc patch for
musl support doesn't account for the name variations of the dynamic
linker. Essentially, when the system boots and starts init, it ends up
looking for a dynamic linker like ld-musl-arm.so.1, when the installed
linker is ld-musl-armhf.so.1, causing init to crash and the kernel to
panic.
I've attached an updated patch that fixes the second issue and adds
support for other platforms from the set maintained here:

I'm not really sure what to do about the first issue, maybe just reinstall
musl after gcc-final? Anyhow, I am going to run another build using a
relative symlink (i.e. ./libc.so) and see if that causes any trouble and
report back.
I'm just reopening this to ping the ticket owner.
