From 5f9fb964c3afbcbc6ca860c817076221d0c1ce8c Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Sun, 5 May 2024 17:48:31 +0200 Subject: [PATCH] bpf: also include toolchain standard header as system header Also include toolchain standard header as system header. These are required by xdp-tools that try to include stddef.h and stdbool.h for some tools. These header are usually in /lib/gcc/../include but musl also have some special variant in /include. To fix compilation of xdp-tools, also include these standard header. These header should follow ISO C standard and should not introduce regression in bpf tools making them specific to an arch.
