Build iPXE binary (undionly.kpxe) to handle http basic authentication

[NiKiZe]

HTTP_AUTH_BASIC is already defined by default
We can see this forum post about syntax and that it should work.

To enable features such as DOWNLOAD_PROTO_HTTPS
you will want to edit src/config/local/general.h (which is created on build if it does not exist and is empty by default)
in this case i would add

Code:

#define DOWNLOAD_PROTO_HTTPS    /* Secure Hypertext Transfer Protocol */

which is copied from src/config/general.h and the #undef is just changed to #define
The define should be in the the same src/config/local/xxx.h filename as it is already in the src/config/xxx.h path.

src/config/local is used so that it is not overriden or causes confilicts on uppstream changes, also note that only changes are defined, do not copy general.h and then enable everything - because that will sooner or later leave you with a build that won't work.

by looking on the ipxe.name.tmp.map file that is generated when building you can see which features was included in the resulting binary,
in this case we can do

Code:

grep https bin/undionly.kpxe.tmp.map

and we can see if any https related code was included or not.
