SYSROOT vs --with-xxx-prefix

[NIIBE Yutaka]

Hello,

Thanks for yor try.  Please have a lock at gnupg/doc/HACKING [0],
and submit your change to dev.gnupg.org or this maling list.
Before your submission, I'd suggest to minimize your change
(e.g. don't include indentation change).

No, the config script (gpg-error-config) never delegates to pkg-config.
It *does* handle the gpg-error.pc file by itself.

We share the gpg-error.pc file between gpg-error-config and pkg-config,
and I'd like to keep deviation by gpg-error-config as small as possible.


Well, I repeat: GnuPG build process never depends on pkg-config.

Today, I push two changes:

    gpg-error-config: Fix the place of *.pc (for multilib).
    9f71b28dcb38e1d5d9001692e2f64009396aaf9b

    gpg-error-config: Add PKG_CONFIG_SYSROOT_DIR support.
    6167f3c461a4e53ccc5af620cdbfa28bfa9234f5

The first one is what you pointed out.
The second one is supporting cross build.
