Yann E. MORIN 31c093e6d0 toolchain/wrapper: make the {str, len} tuple more generic, add comments 
In 61cb120 (toolchain/wrapper: extend paranoid check to -isystem), we
introduced a {str,len} tuple to check the various arguments passed to
gcc, to avoid hard-coding an ever-growing, long list of those args
directly in the condition check.

It was made specific to the arguments (the structure member is named
'arg'), but can also be used to store the unsafe paths as well.

Also, that piece is almost un-documented.

Rename the structure member so that it is more generic, and add a bit of
comments to explain the whole of it.

README 

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
