elfutils uses the argp family of functions, that isn't available in uClibc. So, we add a dependency on argp-standalone if building with uClibc, and modify elfutils source code to link against argp if needed. Heavily based from work done by Stefan Fröberg, but with many further modifications by Thomas Petazzoni.

Allow the usage of an external implementation of the argp functions
|
|
|
|
uClibc lack the argp family of functions that glibc has. Therefore, we
|
|
add a check in the configure script to see if argp_parse is available
|
|
in the C library. If not, we look if it is available in the additional
|
|
'argp' library. If so, we link against that library. If not, we error
|
|
out.
|
|
|
|
This allows to build elfutils against uClibc with an external argp
|
|
library.
