I am doing musl cross compilation using "x86_64-pc-linux-musl-emerge
-v1 sys-libs/musl". It cross compiles it and copies everything into
the folder "/usr/x86_64-pc-linux-musl".
For example "./usr/lib/libc.so" becomes
"/usr/x86_64-pc-linux-musl/usr/lib/libc.so".
"./lib/ld-musl-x86_64.so.1" becomes
"/usr/x86_64-pc-linux-musl/lib/ld-musl-x86_64.so.1". So this
installation breaks all absolute symlinks.
I think the easiest way to fix it will be to keep all symlinks in musl
relative. Now I have "ld-musl-x86_64.so.1 -> ../usr/lib/libc.so" and
it works perfect. Thank you.
