This reverts commit 08fda42141.
These hacks are not necessary any longer since the respective fixes have been applied to LIBC, see
7f3d308fd6 and
ac12fd8873.
On platforms that are not officially supported by GNU Autotools (like OS/2)
it is necessary to generate configure and other related stuff using platform-specific
Autoconf and Automake to make the build succeed. A script autoconf.sh added
by this commit does that.
Note that it's necessary to remove pre-generated upstream versions of these files
from Git completely in order to avoid seeing multiple differences resulting from
different versions of Autotools (and also to save some space - configure files
are huge).
This commit also adds a few minor bits to configure.ac/Makefile.am of a few
projects to help autoconf.sh do its job properly.
Needed for #2.
C++11 supports some C99 features. However OS/2 kLIBC headers do not
support them well.
To workaround, define some feature test macros as built-in. They are
__STDC_CONSTANT_MACROS
__STDC_LIMIT_MACROS
__LONG_LONG_SUPPORTED
Especially, __LONG_LONG_SUPPORTED enables _GLIBCXX_USE_C99 feature in
libstdc++-v3, which use -std=c++98 to test C99 features in C++.

Note: This is a cumulative patch containing the work of several people
which is impossible to separate now.
This patch contains a number of '#ifdef 0'-like hacks that need to be
reviewed and fixed properly as they are unlikely to be accepted upstream
in the current form. Also, some patches may be not relevant any more.
