[PATCH v3 2/4] Drop gnulib fix-base64.patch


From: Robbie Harwood
Subject: [PATCH v3 2/4] Drop gnulib fix-base64.patch
Date: Thu, 27 Jan 2022 14:39:58 -0500

Originally added in 9fbdec2f6b4fa8b549daa4d49134d1fe89d95ef9 and
subsequently modified in 552c9fd08122a3036c724ce96dfe68aa2f75705f,
fix-base64.patch handled two problems we have using gnulib, which are
exerciesd by the base64 module but not directly caused by it.

First, grub2 defines its own bool type, while gnulib expects the
equivalent of stdbool.h to be present.  Rather than patching gnulib,
instead use gnulib's stdbool module to provide a bool type if needed.
(Suggested by Simon Josefsson.)

Second, our config.h doesn't always inherit config-util.h, which is
where gnulib-related options like _GL_ATTRIBUTE_CONST end up.
fix-base64.h worked around this by defining the attribute away, but this
workaround is better placed in config.h itself, not a gnulib patch.
