[RFC PATCH 1/1] bitbake: compile tar-replacement firstly, and not parallel
Compiling tar-replacement or not is decided by version of host tar,
if the host tar version is lower than 1.23, Compiling tar-replacement
is needed.
When doing popoluate tar-replacement sysroot to write the tar to
sysroot, but writing is not finished. other packages probably
use the being written tar to unzip file, which will lead to failure
and report the below error:
"bitbake_build/tmp/sysroots/x86_64-linux/usr/bin/tar: Text file busy "
Now we compile tar-replacement firstly and not parallel to ensure
that a being written tar command will not be used.

Hi:
Building failed several times when building tar-replacement-native is
needed,
The error log shows
"bitbake_build/tmp/sysroots/x86_64-linux/usr/bin/tar: Text
file busy". this log proves "an attempt was made to execute a
pure-procedure
program that is currently open for writing."
Before this error, tar-replacement do_populate_sysroot just starts,
(tar-replacement-native-1.26-r2: task do_populate_sysroot: Started)
After this error, we see tar-replacement do_populate_sysroot just
finish.
So I think the root cause is that do_populate_sysroot sqlite is using
a tar command which being opened to written. in fact, all packages
need tar to do_popolate_sysroot()
I see building tar-replacement-native is started in bitbake file,
could we build tar-replacement firstly, not parallel if needed.

since building tar-replacement or not depends on host tar version, it is
hard to add a tar dependence to any package, and I did not have a good way
to fix this bug except the upper.
Any advice and suggestion are welcome
