Subject: fix: isystem: delete global -isystem compile option (v5.16)
X-Git-Url: https://git.lttng.org/?p=lttng-modules.git;a=commitdiff_plain;h=5987e66c2cba50425d775ce587dd763244373e16

fix: isystem: delete global -isystem compile option (v5.16)

See upstream commit :

  commit 04e85bbf71c9072dcf0ad9a7150495d72461105c
  Author: Alexey Dobriyan <adobriyan@gmail.com>
  Date:   Mon Aug 2 23:43:15 2021 +0300

    isystem: delete global -isystem compile option

    Further isolate kernel from userspace, prevent accidental inclusion of
    undesireable headers, mainly float.h and stdatomic.h.

    nds32 keeps -isystem globally due to intrinsics used in entrenched header.

    -isystem is selectively reenabled for some files, again, for intrinsics.
