Hi, I did some googling without testing.
There is a similar issue here[0], it's caused by an unrecognized flag, please post the configure log related to the error message to see if it's the case. Other posts say gas-preprocessor is a Perl script, it seems the interpreter is not found when configuring. We may add perl as PKG_BUILD_DEPENDS.
