pxelinux and syslinux differ in their handling of absolute paths in menu files. A pxelinux path is aways prepended with the bootfile path while syslinux allows for absolute paths. u-boot was always treating a leading / as an absolute path breaking some pxelinux setups. Fix this by adding a flag to distinguish pxelinux vs. syslinux behavior.

You could also have Tested- or Acked-by from me if desired.
I also took a gander at the syslinux code and found that core/fs/pxe/pxe.c:get_prefix() sets the initial cwd to the prefix. The lookups are done relative to this unless the path is a URL (roughly means it contains "::", see code/comments around the use of PXE_RELATIVE)). In particular a leading "/" isn't specially treated as far as I can see...
