Subject: [PATCH] arm/hafnium: fix kernel tool linking

We need to be sure that the host linker flags are passed to the kernel build,
as otherwise it is possible that binaries are incorrectly linked. For example:

HOSTCC scripts/extract-cert
ld: .../recipe-sysroot-native/usr/lib/pkgconfig/../../../usr/lib/libcrypto.so: undefined reference to `pthread_once@GLIBC_2.34'

Upstream-Status: Inappropriate
Signed-off-by: Ross Burton <ross.burton@arm.com>
