Replace .include with #includefix-include
For some reason, both mipsel-unknown-elf-gcc 8.2.0 and mipsel-non-elf
15.1.0 were unable to resolve .include assembler directives.
As a workaround, it is still possible to use the preprocessor, and
therefore the usual #include preprocessor directive. However, this
requires the assembly files to use the uppercase .S file extension.
