Subject: [PATCH] mpers.m4: more robust test for -m32/-mx32 compile support
When using the default OE toolchain for x86-64, the basic checks for
-m32 and -mx32 compile support in mpers.m4 pass but later attempts to
actually use the toolchain with -m32 fail, e.g.
| In file included from /home/andre/build/tmp/sysroots/qemux86-64/usr/include/sys/syscall.h:31:0,
| from ../strace-4.11/defs.h:55,
| from mpers-m32/kernel_dirent.c:32:
| /home/andre/build/tmp/sysroots/qemux86-64/usr/include/bits/syscall.h:41:29: fatal error: bits/syscall-32.h: No such file or directory
Make the mpers.m4 tests more robust so that configure correctly
detects the limitations of the OE toolchain.
