README-linux: updated to note that strace might not compile

with development kernels
bjm.c: sys_query_module: check if malloc succeeds
system.c: sys_cap[gs]et(): check if malloc succeeds, only malloc once
linux/syscallent.h: updated for 2.3.99pre3
linux/alpha/syscallent.h: updated for 2.3.99pre3, add all osf syscalls
even though Linux doesn't implement them
syscall.c: add global variables for MIPS registers as well
syscall.c: move global variables to before get_scno since that uses them
util.c: oops, misspelled defined
process.c: fix ptrace calls in change_syscall
mem.c: decode sys_madvise
