pre 19.05 feedback: libc port update breaks mkfs from e2fsprogs

[Duss Pirmin]

Hello Genodians

I'm running preparations for the transition to Genode 19.05.

mkfs.run from
https://github.com/trimpim/genode/tree/test-19.05-mkfs_fails fails with
the error message (KERNEL=nova):
"/dev/block: Memory allocation failed while setting up superblock".

Through bisecting I determined, that the libc port update seems to be
the cause of the problem.

dd5aa1748 .. 057a8b0b3 build fails
132ef4dcb compiles, test fails

The error occurs in line 76 in the file
src/noux-pkg/e2fsprogs/lib/ext2fs/inline.c of the contrib code.

Best regards
Pirmin
