[oe] bzip2-native problem

[Yao Zhao]

Hi all,

Got a problem about bzip2-native:

The reason is that when unpacking xextproto-7.2.0.tar.bz2, 
bzip2-native's build is triggered too because of another package's 
dependency. And loader can't find libbz2.so.0 which is in sysroot(host 
bzip2 used libbz2.so.1 so it is sure the libbz2.so.0 in sysroot) I have 
searched the paths in PATH below and only find bzip2 in 2 places: host 
/bin/bzip2 and sysroot bzip2.

In bzip2's Makefile, the install is make -j xxx ... although the install 
is first to install libbz2.so.0 then bzip2 but because of the "-j xxx" 
so it is possible that bzip2 is installed first but libbz2.so.0 is not 
ready yet(in a subshell this link is created).
So I have to make the install atomic or at least don't install in parallel.

so there are a couple of workarounds:
1.set PARALLEL_MAKEINST="" (one line change, and only one library, 2 
binaries installed(bzip2, bzip2recover) + 3 scripts + a couple of links)
2.make a statically linked bzip2 and bzip2recover
3.like perl or python native to make a bzip2-native subdir in sysroot 
then only packages explicitly inherit bzip2native which will set the path.

I need your advice!

thanks,
yao
