sparc: Drop the "-ansi" from the asflags
In the very early kernel 1.x days, assembler files were pre-processed
with the "-traditional" flag. With kernel 1.1.85, the sparc subsystem
was changed to use "-ansi" instead while the other parts of the kernel
continued to use "-traditional". That "-traditional" got removed from
the other architectures in the course of time, but the sparc part
kept the "-ansi" until today.
This is bad since it comes with some disadvantages nowadays: You have
to make sure to not include any header that contains a "//" C++ comment
by accident (there are now some in the tree that use these for SPDX
identifiers for example), and with "-ansi" we also do not get the
pre-defined __ASSEMBLER__ macro which we'd like to use instead of the
kernel-only __ASSEMBLY__ macro in the future.
Since there does not seem to be any compelling reason anymore to use
"-ansi" nowadays, let's simply drop the "-ansi" flag from the sparc
subsystem now to get rid of those disadvantages.
