THIS THREAD IS MY GUESSES WITHOUT REALLY BUILD AT AIX PLATFORM.
Hi, I am new to lua, and trying to cross-compile it to run at arm-linux.
And i read src/Makefile and find some places to update:
patch:
```diff

reproduce:
```shell log

/Library/Developer/CommandLineTools/usr/bin/make echo CC="xlc"

PLAT= guess
CC= xlc
CFLAGS= -O2 -DLUA_USE_POSIX -DLUA_USE_DLOPEN
LDFLAGS= -brtl -bexpall
LIBS= -lm -ldl
AR= ar rcu
RANLIB= ranlib
RM= rm -f
UNAME= uname
```
It should print as below:
```shell log
CFLAGS= -O2 -DLUA_COMPAT_5_3 -DLUA_USE_POSIX -DLUA_USE_DLOPEN -ff1
LDFLAGS= -brtl -bexpall -ff2
```
PS: I wonder whether the reason that somebody doesn't replace CFLAGS
to SYSCFLAGS is that xlc don't support '-Wall -Wextra' args.
