tools/resolve_btfids: Pass HOSTCFLAGS as EXTRA_CFLAGS to prepare targets
Thorsten reported build issue with command line that defined extra
HOSTCFLAGS that were not passed into 'prepare' targets, but were
used to build resolve_btfids objects.
This results in build fail when these objects are linked together:
/usr/bin/ld: /build.../tools/bpf/resolve_btfids//libbpf/libbpf.a(libbpf-in.o):
relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE \
object; recompile with -fPIE
Fixing this by passing HOSTCFLAGS in EXTRA_CFLAGS as part of
HOST_OVERRIDES variable for prepare targets.
