Sorry, I should put more info in the commit message. Yes, it doesn't
make sense to package_rpm, but makes sense to package_ipk (verified)
and package_deb (not yet verified).

My host is X86_64 (doesn't matter)

# Make sure it is a clean build
$ bitbake meta-toolchain -ccleansstate

$ bitbake meta-toolchain

$ find tmp/work/core2-64-poky-linux/meta-toolchain/1.0-r7/sdk/image/ | grep 
poky-linux-gdb
tmp/work/core2-64-poky-linux/meta-toolchain/1.0-r7/sdk/image/opt/poky/1.6+snapshot/sysroots/x86_64-pokysdk-linux/usr/bin/x86_64-poky-linux/x86_64-poky-linux-gdb
#### Note gdb-cross has been installed

$ find tmp/work/core2-64-poky-linux/meta-toolchain/1.0-r7/sdk/image/ | grep ncurses
### No output, libncurses.so isn't installed.

And if we use PACKAGE_CLASSES = "package_rpm", we can see that libncurses.so
is installed.

This is because:

$ rpm -qpR 
tmp/deploy/rpm/x86_64_nativesdk/gdb-cross-canadian-x86-64-7.7.1-r0.x86_64_nativesdk.rpm 
| grep ncurses
libncurses.so.5()(64bit)
### There is a file depends (libncurses.so.5)

$ dpkg-deb -I 
tmp/deploy/ipk/x86_64-nativesdk/gdb-cross-canadian-x86-64_7.7.1-r0_x86_64-nativesdk.ipk 
| grep ncurses
### No output, ipk knows nothing about the file depends (libncurses.so.5),
### so that it would not be  installed.

I updated the commit message in the repo, please feel free to let me know if
you have any questions.

We had nativesdk-ncurses in the DEPENDS, also need add
nativesdk-ncurses-libncurses to the RDEPENDS, otherwise libncurses will
not be installed when PACKAGE_CLASSES = "package_ipk" or deb.

Fixed:
- Set these in local.conf:
   MACHINE = "qemux86-64"
   PACKAGE_CLASSES = "package_ipk"

$ bitbake meta-toolchain
$ find tmp/work/core2-64-poky-linux/meta-toolchain/1.0-r7/sdk/image/ | grep ncurses
   ## No output, ncurses isn't installed, but it should.
