Subject: jump label: pass kbuild_cflags when checking for asm goto support

From: David Lin <[email protected]>

[ 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.
