Thanks for working on this again. Can you submit your or1k and
microblaze changes back to the upstream double-conversion project (and
perhaps also Qt5) ?

This uClibc issue is something for Waldemar. I'm personally still a bit
impressed by the magic of qemu user mode emulation.

That's weird, I have a musl toolchain here (installed from an external
toolchain), and its symlink is relative:

$ ls -l output/staging/lib/{ld-musl*,libc.so}
lrwxrwxrwx 1 thomas thomas     14 Aug 21 22:14 output/staging/lib/ld-musl-armhf.so.1 -> ../lib/libc.so
-rwxr-xr-x 1 thomas thomas 740772 Jun 26 00:08 output/staging/lib/libc.so

Applied to master. Thanks!

Thomas
