Fork

I forgot to kill these files in my last commit.

This is based on a patch posted to lkml by Petr Baudis on 23 Nov, which was
then considerably hacked up by me. This eliminates the separate lxdialog and
instead directly uses the lxdialog internals. This allows 'make menuconfig'
to be much faster.

Implement the rest of the missing include/net/if.h interfaces

Looks like this is in fact needed to properly debug dynamically
linked stuff, so put it back but add a check for NULL

Override optimization settings when debugging

Fix the other instance of getcwd

For now, always claim we have exactly one cpu. It should
generally be the truth...

Properly allocate memory when size is 0, but so is buf

Make the arm cpu-specific optimizations work properly

Don't leak outside of the target area when installing things.

Spelling fixes

Cut and paste error.

Forgot one...

Add hsearch and hsearch_r. Consolidate all functions prototyped in
search.h in one directory.

If the wait failed in pclose it would return a random status code
instead of -1 as expected.

Make ldd work even more like GNU ldd by appending dummy load addresses

I forgot to include features.h

Silly me, I forgot to include features.h

Kill a bit of unused cruft

Fix compilation on mips

Make support for global constructors and global destructors be
configurable, so people who do not need or want ctor/dtor support
can disable it and make their binaries a little bit smaller.
-Erik

Fixup sysconf to report the correct answer when UCLIBC_DYNAMIC_ATEXIT
is enabled.

Fix an ifdef mismatch.

Fix the defaults to make them be sane

Fix bug in setting daylight and timezone when no (valid) TZ.
Bug reported by Arne Bernin <arne@alamut.de> in regards to freeswan.

Oops.. left in a bit of debugging code.

Use 'install' rather than 'mkdir -p' for target directories.
Add $(PREFIX) to avoid leaking things at install time.
-Erik

Ok... here's the summary:
Hopefully locale support will build when cross compiling now. Collation is
still not supported, but that's what I'm currently working on. In the
next couple of days, I'll probably put up a couple of files for download
that will save people the trouble of generating all the glibc locales.
Added *wprintf functions, although they currently don't support floating
point. That will be fixed when I rewrite _dtostr... or possibly before.
Added the wcsto{inttype} functions.
Added iconv() and a mini iconv utility. The require locale support and
only provide for conversions involving the various unicode encodings
{ UCS-4*, UCS-2*, UTF-32*, UTF-16*, UTF-8 }, the 8-bit codesets built
with the locale data, and the internal WCHAR_T.

Oops. As Pavel Roskin notes, I forgot to conditionally include
the __fsetlocking call in libc/unistd/usershell.c. It should
be wrapped and only included if __UCLIBC_HAS_THREADS__ is defined.

Doh! As Stefan Allius points out, I forgot to properly review
this change.
