Previous code just checked if any new file was created.
New code checks existance of the file created by MXE in case
a build succeeded: "usr/<target>/installed/<package>".
Without this improvement, some packages (e.g., pango) were
falsely reported to be built successfully, because they have
two or more targets and only first target succeded, creating
*some* files (but not file "usr/<target>/installed/<package>").
There are documentation and other shared files installed,
which we don't need [1]. Some packages install files to same
paths. There is a list of all packages which overlap and
shared files [2].
Create a list of packages which have common files across
targets. Some of them are a part of compiler chain (gcc-*),
some are built natively intentionally:
* gcc-isl
* gcc-mpc
* gcc-gmp
* gcc-mpfr
* gcc
* yasm
* ncurses
* pkgconf

After commit b14c1a3a9c , packages could not
be installed on Debian <= Wheezy, because it lacks package
libtool-bin. So package mxe-requirements should depend on
libtool-bin only for Debian >= Jessie.
This commit changes the function that builds packages
mxe-requirements. Now it makes 4 .deb files:
wheezy/
mxe-requirements_2.23_i386.deb
mxe-requirements_2.23_amd64.deb
jessie/
mxe-requirements_2.23_i386.deb
mxe-requirements_2.23_amd64.deb
see #754
