[build] Mark weak functions noinline
Weak functions whose visibility is hidden may be inlined due to a bug
in GCC. Explicitly mark weak functions noinline to work around the
problem.
This makes the PXE_MENU config option work again, the PXE boot menu
was never being called because the compiler inlined a weak stub
function.
The GCC bug was identified and fixed by Richard Sandiford
<rdsandiford@googlemail.com> but in the meantime iPXE needs to
implement a workaround.
