2024-09-22linux-user,loongarch: move to syscalltbl fileLaurent Vivier4-324/+440
Since kernel v6.11 loongarch has moved from syscall_nr.h file to syscall.tbl (26a3b85bac08 ("loongarch: convert to generic syscall table")) Update linux-user scripts to be able to retrieve syscall numbers from linux syscall.tbl instead of syscall_nr.h. New syscall.tbl is imported from linux v6.11 using updated scripts/update-syscalltbl.sh Remove scripts/gensyscalls.sh that is now useless.
