This avoids relocation overflows in sparc/sparc64 targets while
linking, where the reachable data using -fpic is only 4kb.

The -fsanitize=undefined check need to use AC_LINK_IFELSE to make sure
libubsan is installed. When doing undefined checking we should disable
ALLOW_UNALIGNED memory accesses to catch issues where we do unaligned
accesses by accident.

Due to missing symbol versioning support in uClibc calls to versioned
functions that internally call different version of themselves results
in infinite recursion.
Introduce macro SYMBOL_VERSIONING and use it instead of plain SHARED to
decide whether symbol versioning is needed. Control this macro
definition with new configure option --disable-symbol-versioning.

For Dwarf_Abbrev codes, the most common case is that they're packed at
the low end, saving uleb128 encoding size. Since the hash table is
always resized to be no more than 90% full, those codes are always less
than the table size, and dividing for the remainder is unnecessary.
Dwarf_Dies are frequently created anew, and need to find abbrev each
time, so even that one division becomes a noticeable hotspot. This
patch adds a branch to avoid it, which is very predictable for the CPU.

autoreconf will install config/test-driver, ignore it.
Update gettext m4 and po files to version 0.18.2.
Use AM_CPPFLAGS instead of INCLUDES.
All changes are backward compatible with Automake 1.11.
Ran into a situation where pread was returning less data than requested for
remote files on a networked filesystem. This patch modifies the IO wrappers
to request the remaining data as long as no real errors occured.
