[Buildroot] [PATCH 0/2 v3] toolchain/wrapper: add more paranoid checks (branch yem/wrapper)

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

This short series introduces more paranoid checks for unsafe paths, and
reports offending options.


Changes v2 -> v3:
  - also handle -idirafter and -iqupte  (Arnout)
  - simplify the code doing the checks  (Thomas)
  - drop stray variables  (Thomas)
  - comment the tricky code  (Thomas)
  - document what unsafe options are; document the checking function

Changes v1 -> v2:
  - don't use a variadic function, use explicit args  (Arnout)
  - -isystem is not always separated from its path  (Arnout)
  - simpler error reporting  (Arnout)
  - add a list of unsafe options and iterate over it; makes it easier to
    handle even more unsafe options


Regards,
Yann E. MORIN.
