Subject: [PATCH] meson.build: make TLS ELF optional
|
|
USE_ELF_TLS has replaced GLX_USE_TLS so this patch is the original "make
|
TLS GLX optional again" patch updated to the latest mesa.
|
|
For details, see:
|
https://gitlab.freedesktop.org/mesa/mesa/-/issues/966
|
|
This prevents runtime segfault on musl:
