Subject: jump label: pass kbuild_cflags when checking for asm goto support
From: David Lin <dtwlin@google.com>
[ 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.
