From 1948d0afe43ec3792766b58d750e3ded88735929 Mon Sep 17 00:00:00 2001 From: David Lin Date: Tue, 23 May 2017 21:53:55 -0400 Subject: jump label: pass kbuild_cflags when checking for asm goto support [ Upstream commit 35f860f9ba6aac56cc38e8b18916d833a83f1157 ] Some versions of ARM GCC compiler such as Android toolchain throws in a '-fpic' flag by default. This causes the gcc-goto check script to fail although some config would have '-fno-pic' flag in the KBUILD_CFLAGS. This patch passes the KBUILD_CFLAGS to the check script so that the script does not rely on the default config from different compilers.
