commit 60dabb5b1d6d ("pxe: Make the SENDCOOKIES feature for HTTP worked
again") introduced a regression for ldlinux because it references the
'SendCookies' symbol, which is only provided by PXELINUX.

The regression was caused because the '__weak' tag was dropped from the
declaration of SendCookies.

There is a typo in the path used to decide whether to build gnu-efi.
Since the condition "does a nonexistent file exist?" will never evaluate
true, we're currently building gnu-efi unnecessarily.

Guard against future changes by requiring that the gnu-efi build scripts
exit with success.

Modify the scripts to check that they're called with the correct number
of arguments and error out otherwise after printing some helpful info.

This change also stops relying on passing arguments through environment
variables and instead passes them explicitly to the scripts, which is
definitely more robust, and handles the case where the scripts are
invoked directly.

Of course, now that the scripts can be invoked directly we need to
regard any input as hostile and exit immediately on error.

Now that we have a gnu-efi git submodule we need some scripts to build
and install it into architecture-specific build directories.

This actually simplifies things a bit because we no longer need to
account for the variations in distribution installation paths - we now
control the paths.

Tracking the gnu-efi dependency has tripped up some users. We can make
things easier when building Syslinux by including a copy of the gnu-efi
source and building it for efi32 and efi64.

Code refactoring had caused the http_bake_cookies() function to become
inaccessible and the SendCookies variable to be duplicated, causing
the sendcookies feature to not work.
