configure: simplify options parsing
|
|
|
|
This commit simplifies options parsing moving all the code not related to
|
|
parsing out of the case statement.
|
|
|
|
- The conditional shift after the assignments is moved right after the
|
|
case, reducing code duplication.
|
|
- The semantic checks on the LIBBPF_FORCE value is moved after the loop
|
|
like we already did for INCLUDE and LIBBPF_DIR.
|
|
- Finally, the loop condition is changed to check remaining arguments, thus
|
|
making it possible to get rid of the null string case break.
|
|
|
|
As a bonus, now the help message states that on or off should follow
|
|
--libbpf_force
