meson: linux-user The most interesting or most complicated part here is the syscall_nr.h generators. In order to keep the generation logic all in meson.build, I am adding to config_target the name of the .tbl file, and making the generated file syscall<SUFFIX>_nr.h for input file syscall<SUFFIX>.tbl. For architectures where the input file is not named syscall_nr.tbl, syscall_nr.h has to be a source file; it's just a forwarder for x86 (i386/x86_64), while for MIPS64 it chooses between N32 and N64 ABIs.
