scripts: check host features with host compiler

Currently, we check host feature in ./configure. This works only for
cross toolchains, but not for canadian toolchains. ./configure has
absolutely no way to know what the host for the toolchain will be;
only the build scripts know.

So, move the headers & libraries checks from ./configure to the build
scripts, early enough in the build, but not before we know the host
compiler and other tools.

      A static cross gdb can be usefull if you debug on a machine that is
yann@1915
    22
      not the one that is used to compile the toolchain.

yann@1915
    24
      That way, you can share the cross-gdb without installing a toolchain
yann@1915
    25
      on every machine that will be used to debug target programs.

      Say 'y' if you want to use Python scripting inside gdb.
yann@2703
    34
      Say 'n' if you do not want to.

yann@2703
    36
      Beware that enabling Python scripting could render the gdb
yann@2703
    37
      executable non-functional if you move it to another machine.
yann@2703
    38
      Building a static gdb can help in this regard, although there
yann@2703
    39
      have been reports of problems when linking gdb to the static
yann@2703
    40
      libpython.a. This should be fixed in gdb >=7.3. YMMV.
