[Buildroot] [PATCH 1/1] package/glibc: bump version for more post-2.28 fixes

[Mark Corbin <mark.corbin@embecosm.com>]

This update includes two specific fixes that have been backported
to the glibc 2.28 release branch from the glibc master branch:

1) UAPI header file asm/syscalls.h has been merged into the UAPI
asm/unistd.h header file for the RISC-V architecture in the
4.20 kernel. This causes the glibc 2.28 build to break.

2) sysdeps/ieee754/soft-fp: ignore maybe-uninitialized with -O
[BZ #19444]. The current patch for this issue can now be dropped
from Buildroot.
