Max Filippov 30a3b08c17 argp-standalone: restrict value range passed to isprint function
According to C standards isprint argument shall be representable as an
unsigned char or be equal to EOF, otherwise the behaviour is undefined.

Passing arbitrary ints leads to segfault in nm program from elfutils.

Restrict isprint argument range to values representable by unsigned char.

Note: a similar change was done to the internal argp implementation of
glibc in commit
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=9055724a92433ffa4c36f93d918ee1b3dfa1d6f7.

[Thomas: add a reference to the corresponding glibc fix.]

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.
