[Buildroot] [PATCH 1/1] package/wpewebkit: import patch to support uclibc

[Yann E. MORIN <yann.morin.1998@free.fr>]

Adrian, All,

On 2021-05-26 21:38 +0300, Adrian Perez de Castro spake thusly:
> Import a small patch from the upstream Bugzilla which is needed to allow
> building WPE WebKit against uClibc.

> Signed-off-by: Adrian Perez de Castro <aperez@igalia.com>

Applied to next, thanks.

I just added the references to the upstream commit you provided on IRC,
and added the name of the upstream reviewer to more closely match
upstream's commit log.

Ditto the webkitgtk patch, of course.

Regards,
Yann E. MORIN.
