Subject: infra: /usr support: STAGING_DIR can be outside BASE_DIR
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6f638ea9c9c7bacc646430a74ad3dd2740eae676;p=buildroot.git

infra: /usr support: STAGING_DIR can be outside BASE_DIR

If the user sets a custom BR2_HOST_DIR, then STAGING_DIR is not under
BASE_DIR. The .pc/.la file fixup commands incorrectly made this assumption
and thus should be corrected.

Additionally, this patch:
- rewords the comment in pkg-autotools that explains the replacements.
- removes a for statement in favor of xargs
