numpy and scipy FTBFS due to LDFLAGS pollution

Upstream says it's normal for them to fail if LDFLAGS is set, but I've no idea why they haven't failed before now.

This bug was fixed in the package python-numpy - 1:1.0.4-6ubuntu1

---------------
python-numpy (1:1.0.4-6ubuntu1) hardy; urgency=low

  * Sync from debian unstable.
    - All existing Ubuntu changes are now in Debian.
  * debian/rules: Unset LDFLAGS, as numpy's distutils is braindead and FTBFS.
    (LP: #199031)
  * debian/python-numpy.links: Reference /usr/share/pyshared, rather than the
    old python-central-specific directory.
  * debian/control: Comply with DebianMaintainerField.

python-numpy (1:1.0.4-6) unstable; urgency=low

  [ Kumar Appaiah ]
  * Remove unnecessary README.numpy-dbg.
  * debian/control:
    + Build using gfortran, libblas-dev, liblapack-dev. (Closes: #464784)
    + Conflict with python-scipy (<= 0.6.0-6), python-matplotlib (<< 0.90.1-3),
      built with g77.
    + Add build-conflict with atlas3-base-dev.
    + Build again using python-central as done up to version 1:1.0.4-2.
    + Spell python with small `p', as per new description norms.
  * debian/rules:
    + Add proper symlinks in /usr/include/python<version>/numpy
      for numpy headers.
    + Include symlinks for debug package.
  * debian/python-numpy.links:
    + Symlink old numarray headers to numpy include directory.
      (Closes: #463007)
  * debian/copyright:
    + Fix by adding copyright date and symbol.

  [ Ondrej Certik ]
  * Package description update: python -> Python (fixes a lintian warning)

This bug was fixed in the package python-scipy - 0.6.0-8ubuntu1

---------------
python-scipy (0.6.0-8ubuntu1) hardy; urgency=low

  * Sync from Debian unstable.
    - Builds with gfortran, so is installable again. (LP: #187004)
  * debian/rules: Fix a few FTBFSes (LP: #199031):
    - Don't remove LICENSE.txt, or python-central gets angry.
    - Make sed look for stuff in /usr/share/pyshared, rather than the old
      python-central directory.
    - Unset {LD,F}FLAGS, as it FTBFS otherwise due to a braindead distutils.
  * debian/control: Comply with DebianMaintainerField.

python-scipy (0.6.0-8) unstable; urgency=low

  * Build depend on libsuitesparse (>= 3.1.0-3)
  * Build depends fixed to use gfortran based lapack and blas (Closes: #466868)

python-scipy (0.6.0-7) unstable; urgency=low

  * Bumped the version, because python-numpy conflicts with python-scipy (<=
    0.6.0-6). This compiles against the old suitesparse, but it makes the
    package installable and working again.

python-scipy (0.6.0-6) UNRELEASED; urgency=low

  * debian/control
    - uniforming both Vcs-Svn and Vcs-Browser fields
