Changqing Li 07083caab6 rpm: fix file conflicts for MIPS64 N32
The following error occurred when prefer_color set to 2:
Error: Transaction check error:
  file /sbin/ldconfig conflicts between attempted installs of
ldconfig-2.31+git0+71f2b249a2-r0.mips64_n32 and
lib32-ldconfig-2.31+git0+71f2b249a2-r0.mips32r2
  file /usr/bin/gencat conflicts between attempted installs of
lib32-libc6-utils-2.31+git0+71f2b249a2-r0.mips32r2
...

This was because:
transactions_color = 001 (ELF32) & 010 (ELF64) & 100 (ELF32 N32 MIPS64)
FColor = Current file color (001) & transaction_color (111)
oFcolor = Previous file color (100) & transaction_color (111)

when "neither preferred" happened, handled as conflicts. this is too
restrictive for three way conflicts(mips64/mips64 n32/mips(32)).
Fixed by  perform a 'last-in-wins' resolution when "neither is preferred".

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
