i activated BR2_CCACHE=y and my build is broken with this error, seems like optimization flag is not passed down to compiler

    Run Build Command(s):/usr/bin/make cmTC_72e6a/fast && make[1]: Entering

option -- 'O'
Usage:
ccache [options]
ccache compiler [compiler options]
compiler [compiler options] (via symbolic link)

Common options:
-c, --cleanup delete old files and recalculate size
counters
(normally not needed as this is done automatically)
-C, --clear clear the cache completely (except
configuration)
-F, --max-files=N set maximum number of files in cache to N
(use 0
for no limit)
-M, --max-size=SIZE set maximum size of cache to SIZE (use 0 for
no
limit); available suffixes: k, M, G, T
(decimal)
and Ki, Mi, Gi, Ti (binary); default suffix:
G
-p, --show-config show current configuration options in
human-readable format
-s, --show-stats show summary of configuration and statistics
counters in human-readable format
-z, --zero-stats zero statistics counters

-h, --help print this help text
-V, --version print version and copyright information

Options for scripting or debugging:
--dump-manifest=PATH dump manifest file at PATH in text format
-k, --get-config=K print the value of configuration key K
--hash-file=PATH print the hash (<MD4>-<size>) of the file at
PATH
--print-stats print statistics counter IDs and
corresponding
values in machine-parsable format
-o, --set-config=K=V set configuration item K to value V

--- Comment #2 from Frank Wunderlich <[email protected]> --- mhm, seems to be fixed in 2020.11-825...ccache is also created in ~/.buildroot-ccache (298 MB)

btw. is there a way to make clean but leave compiled toolchain (i want to compile for armhf and aarch64)?
