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

[Jean Weisbuch]

It was in fact the "config/local/" folder that wasnt clean (general.h, 
general.h.efi and colour.h were not empty).

I got fooled by the "make clean" that didnt clean this folder and as it 
has a .gitignore "*", there wasnt any change reported by "git status".

Shoudnt "make clean" be cleaning these files (or maybe add a distclean)?
