[Qemu-devel] [Bug 902306] [NEW] qemu-user -static variants require shared libraries

[Vagrant Cascadian]

Public bug reported:

somehwere in the qemu 1.0 series, the qemu-user static  variants started
issuing build warnings like so:

  
/usr/lib/gcc/i486-linux-gnu/4.6/../../../i386-linux-gnu/libglib-2.0.a(gutils.o):
 In function `g_get_any_init_do':

requires at runtime the shared libraries from the gli
  bc version used for linking

for a full log, see:

https://buildd.debian.org/status/fetch.php?pkg=qemu&arch=amd64&ver=1.0~rc4%2Bdfsg-1&stamp=1322591568

i've also tested with qemu/master from today (commit
217bfb445b54db618a30f3a39170bebd9fd9dbf2), and it has the same issue.

This seems to cause adduser, addgroup, etc. to fail in cross-
architecture chroots that use statically built qemu-user binaries to
emulate the foreign architecture.

Older versions (0.12-0.15, at least) didn't seem to have this issue.
