[Buildroot] [PATCH] docs/manual: add a 'Known issues' chapter

[Thomas Petazzoni]

Add a 'Known issues' chapter, which lists the exceptions I have
currently in the autobuilder scripts to avoid known problems from
occuring. I believe it is more useful to document them rather than
keeping them hidden in my autobuilder script.

The uClibc dependencies are already documented in Config.in, but ok.

In all 3 sections.

I believe we have a lot of other situations with packages triggering
internal compiler errors, especially for microblaze and avr32.

Committed with these changes, thanks.

For all these 3 packages that miss options in the default uClibc
configuration,
there are comments in the Config.in files mentioning what are these missing
options.
It is weird to list them for ltp-testsuite, but not for xfsprog or mrouted.

[Buildroot] [PATCH] docs/manual: add a 'Known issues' chapter

Dear Peter Korsgaard,

I agree, but I'm merely documenting the exceptions I've added in my
autobuilders script. I'm planning on adding similar exceptions and
documentation in this "Known issues" section for the other compiler
failures as well.

Best regards,

Thomas
