bluez: Fix linking with lld linker

Recent upgrades have been breaking with LLD as linker

aarch64-yoe-linux-ld.lld: error: undefined symbol: __stop___debug
>>> referenced by log.c:0 (/usr/src/debug/bluez5/5.86/../sources/bluez-5.86/src/log.c:0)
>>>               src/log.o:(__btd_log_init)

This is described in LLD docs as well [1]
