[Buildroot] buildroot Digest, Vol 71, Issue 9

[Stijn Souffriau]

Hello Thomas,

I can fix all the minor issues, no problem. For me, the only two bigger 
issues are:

  - uClibc support: glibc specific headers seemed to be needed in order 
to build. Maybe I can remedy that but I'm not sure. Can't you ignore 
this for now so that I or somebody else can add uClibc support later? If 
it's a problem I'll look into it but my time is limited.
  - host-gnupg: I needed it to sign file system images (useful for 
remote upgrades). I'm not sure if buildroot will always build host-gnupg 
and if this is a problem for you, if so I can always make it optional it 
with yet another config option.

Thanks for the feedback,

Stijn
