From 74958c3e341de713b596c8cfd35b2391d6c7bc09 Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>
Date: Thu, 7 Jan 2016 18:19:03 +0000
Subject: [PATCH] build: Add option to select libc implementation
There are more than glibc for C library implementation available on
linux now a days, uclibc cloaked like glibc but musl e.g. is very
different and does not implement all GNU extensions.
Disable tests specifically not building _yet_ on musl based systems
Upstream-Status: Pending (pvorel: this is not going to be fixed, instead
each test needs to be fixed)
rt_tgsigqueueinfo fails with:
rt_tgsigqueueinfo01.c: In function 'sigusr1_handler':
rt_tgsigqueueinfo01.c:42:22: error: 'siginfo_t' {aka 'struct <anonymous>'} has no member named '_sifields'; did you mean '__si_fields'?
42 | sigval_rcv = uinfo->_sifields._rt.SI_SIGVAL.sival_ptr;
| ^~~~~~~~~
| __si_fields
