Bump the relibc submodule to d9760bdc which replaces the
getifaddrs() ENOSYS stub with a real implementation that walks
/scheme/net/ifs/ via SYS_GETDENTS and reads each interface's
flags, ip, and netmask. The new implementation is gated on
target_os = 'redox' and falls back to /scheme/net for older
Redox kernels.
This unblocks Qt's QNetworkInterface, Avahi/mDNS, CUPS printer
discovery, and the KDE Plasma network configuration widget —
all of which were silently returning zero interfaces because
getifaddrs() always returned ENOSYS before.
The full canonical build (./local/scripts/build-redbear.sh
redbear-mini) requires a prefix rebuild to regenerate the
prefix's libc.a; this is what 'touch relibc && make prefix'
does in the Redox build system.
