@item --enable-host-bind-now
Specify that the @emph{host} executables should be linked with the option
@option{-Wl,-z,now}, which means that the dynamic linker will resolve all
symbols when the executables are started, and that in turn allows RELRO to

Specify that the compiler should assume that the
assembler it finds is the GNU assembler. However, this does not modify
