wrapper: improve blacklist handling
Explicitly disable build-id if it is blacklisted. It may be enabled by
default in the toolchain.
Use TARGET_HARDEN_STACK to blacklist all stack protector options.
Note: With 'dash', variables for a specific command remain set afterwards
if the command is a shell function. Use '()' to make sure the existing value
is not overwritten.
