Currently, uClic++ 0.2.5 fails to compile when using a long filepath.
For example, if the openwrt directory is in the path:
/tmp/this_directory_name_is_very_long/more_long_paths/.../openwrt,
then uclibc++ will cause a very obtuse error.
Although the uclibc++ makefiles do print a "File name too long" error,
it's not the final error that's printed, so it's a bit confusing:
> /bin/sh: 1:
> cannot create src/abi/libsupc/<SNIP>_libsupc++.a.dep: File name too long
> <SNIP: some other makefile output here>
> array_type_info.o: No such file or directory
Although OpenWRT 22.03 and current master branch have removed uClib++,
I thought I'd make a PR for OpenWRT 21.02, since I encountered it
and there seems to be quite a few other people experiencing the same issue.
It especially happens when using the SDK, (or when using an encrypted fs)
since the pre-packaged SDKs have very long filenames.
This patch is already in upstream [1], but has not yet been released.

The first allows usage of several functions in the std namespace, which
broke compilation of gddrescue specifically with uClibc-ng and uClibc++.
The second allows usage of long long with normal C++11, which is part of
the standard. Before, std=gnu++11 needed to be passsed to work around it.
As a result of the second patch, the pedantic patch can safely be removed.
Both patches are upstream backports.
Added -std=c++11 to CFLAGS to guarentee proper inclusion of long long.
Added another patch that fixes a typo with the long long support. Sent to
upstream.
Fixed up license information according to SPDX.
Small cleanups for consistency.

This patch was originally added to fix compilation with v4l2rtspserver.
Turns out it was v4l2rtspserver that was broken, not uClibc++. This now
causes issues with a different package where the arguments are being
split.
Note that with this patch, shellcheck throws an error:
SC2068: Double quote array expansions to avoid re-splitting elements.

Switched to xz archives for smaller size.
Removed upstreamed patches.
Reorganized Makefile a little bit for clarity. Build/Prepare is not useful
anymore. Upstream converted the file to LF.
Refreshed config.
Removed -ansi option from the original CFLAGS as this was causing long
long support to be missing.
Removed fPIC. We have the macro $(FPIC) already used. No point in setting
fpic and fPIC together.
Removed pedantic -Wlong-long warnings as they are not useful.
Removed -std=gnu++98. Not only is it unnecessary (it compiles against all
standards), it actually results in a size increase. 75843 vs. 75222 (gcc
in OpenWrt defaults to g++14).
Added --gc-sections to linker flags to reduce size: 72653 vs 75222.
Removed warn linker options. They have been upstreamed.
Tested on Archer C7v2 and GnuBee PC1.

When calling erase() on a containers derived from __base_associative
(e.g. multimap) and providing a pair of iterators a segfault will
occur.
Example code to reproduce:
typedef std::multimap<int, int> testmap;
testmap t;
t.insert(std::pair<int, int>(1, 1));
t.insert(std::pair<int, int>(2, 1));
t.insert(std::pair<int, int>(3, 1));
t.erase(t.begin(), t.end());
