The reason is that ccache does not recognize and process the .incbin
directive, so caching is unreliable.

Update ccache 3.3.2 and refresh patch
Preserving the original patch comments here by Karl Vogel:

Subject: [PATCH] Include environment variable GCC_HONOUR_COPTS in hash.
The OpenWRT patch, 910-mbsd_multi.patch, to GCC adds an extra
compilation flag, -fhonour-copts, which is influenced by an
environment variable called GCC_HONOUR_COPTS.
Include this environment var in the hash calculation as otherwise
the gcc stdout warning from a previous compilation might be shown
where, even when GCC_HONOUR_COPTS is in 's'ilent mode.

The OpenWRT GCC patch, 910-mbsd_multi.patch adds an extra option
to gcc that depends on an environment variable. Standard ccache
is unaware of this option and therefor can produce stdout from gcc
that doesn't correspond to what you would get if you actually
do a direct compilation with gcc.
This commit adds a patch to ccache to make it aware of the new
option and removes the feature from the ccache package to use the
host system's installed ccache binary.
