Paulo Matos 9dcca3ae40 package/qemu: fix qemu 3.1.1.1 to build with glibc-2.29
These patches are already in qemu upstream under:
- 184943d827ce09375284e6fbb9fd5eeb9e369529
- 71ba74f67eaca21b0cc9d96f534ad3b9a7161400

They rename gettid() to sys_gettid() to avoid clash with glibc

Subject: [PATCH] linux-user: assume __NR_gettid always exists
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The gettid syscall was introduced in Linux 2.4.11. This is old enough
that we can assume it always exists and thus not bother with the
conditional backcompat logic.
