Hello Maintainers:
After tried, I guess related binutils and gcc are not match with each
other: gcc support "-minim" option which will pass to gas, but gas can
not recognize it.
With "-mno-minim" option, we can try to bypass this issue (I am just
trying), but it seems not a quite good idea.
Welcome any additional suggestions or completions for it, thanks.
The related error with making manually ("make menuconfig; make" in root
directory also get the same issue):
