Attachments: Patch for cross-pkg-config to handle --help

Description Alexandra Parker 2022-01-09 10:29:45 UTC 
Some ebuilds like www-servers/apache call pkgconf with a --help flag just to see if it works. cross-pkg-config should just pass the --help flag to pkgconf and not try to parse the results. Attached is my unsophisticated take on a solution.

Reproducible: Always

Steps to Reproduce:
1. arm-unknown-linux-gnueabihf-emerge apache
Actual Results:  
 * Could not execute /usr/arm-unknown-linux-gnueabihf/tmp/portage/www-servers/apache-2.4.52/temp/pcre-config; do you have bad mount                                                                                                                                               
 * permissions in /usr/arm-unknown-linux-gnueabihf/tmp/portage/www-servers/apache-2.4.52/temp or have TPE turned on in your kernel?                                                                                                                                               
 * ERROR: www-servers/apache-2.4.52::gentoo failed (configure phase):                                                                                                                                                                                                             
 *   check your runtime settings #500928

Expected Results:  
Emerged apache

    cross-pkg-config: allow basic options for $1
    
    Tools sometimes probe pkg-config to see if it itself works.  Allow
    those basic options through.  We specifically don't parse the full
    command line to keep the code simple, faster, and to avoid dealing
    with ugly edge cases (like `pkg-config -- --help`).
