[RFC PATCH 0/8] sysroot support

[Paolo Bonzini]

This patch series is on top of 04329d83555b5f8d2fd02428418a79ea392b2d91.
The basic idea is to look for -L= and -R= to expand the sysroot, and for
the sysroot to remove it in .la files.

Some missing testcases are hinted at in sysroot.at.  I think they would
already work with the patch as is.  However, I haven't retested this at
all, so I trust my old runs from mid 2009 which were done with Fedora 12
and its mingw cross-compilation environment.

Sorry for the delay.

Paolo Bonzini (8):
  handle sysroot flags
  fix buglet
  provide shell functions to configure
  Add --with-sysroot
  add a basic sysroot test
  teach libtool -L= and -R=
  handle sysrooted paths when reading dependencies to la files
