[ipxe-devel] ipxe.efi does not compile (hidden symbol _etextdata isn't defined)

[Jean Weisbuch]

While undionly.kpxe and ipxe.lkrn are compiling without any issue, i 
cannot compile ipxe.efi using the latest code from GitHub on a Debian 
Squeeze amd64 :

    # git fetch --all
    Fetching origin
    # git reset --hard origin/master
    HEAD is now at 7cfdd76 [block] Describe all SAN devices via ACPI tables
    # git pull origin master
     From git://git.ipxe.org/ipxe
      * branch            master     -> FETCH_HEAD
    Already up-to-date.

    cd src/
    # make bin-x86_64-efi/ipxe.efi

Is there any specific parameters to set on general.h to compile the efi 
binary?
