* build-package.sh: allow for arrays in TERMUX_PKG_{SRCURL,SHA256}
Packages that require several source archives can then set these parameters to
arrays instead of downloading them "manually" in termux_step_post_extract.
Downloaded files are extracted into subfolders in TERMUX_PKG_SRCDIR.
Tested for backward compatibility in a couple of packages and the combinations
tar + tar, zip + tar, tar + zip, zip + zip.
* perl: download perl-cross through TERMUX_PKG_SRCURL
* perl: remove $PREFIX/{lib/libperl.so,include/perl} before build
Otherwise building perl twice doesn't give the same results, symlinks are
messed up.
Also remove old remnant from when there was a Kid.pm.patch.
* bash: fix tiny typo
* ecj: remove hardcoded SHA256 and pkg version
* elfutils: download argp-standalone through TERMUX_PKG_SRCURL
* ldc: download all src archives through TERMUX_PKG_SRCURL
* libgc: download libatomic_ops through TERMUX_PKG_SRCURL
* libllvm: download all src archives through TERMUX_PKG_SRCURL
* linux-man-pages: download src archives through TERMUX_PKG_SRCURL
* ncurses: download all src archives through TERMUX_PKG_SRCURL
* pngquant: download lib sources through TERMUX_PKG_SRCURL
Use .zip for lib since the downloaded archives are otherwise both named
$TERMUX_PKG_VERSION.tar.gz and replace each other. This causes caching to
not work.
The libintl.so library was a symlink to libandroid-support. We
now provide the functions inline in libintl.h so libintl.so has
been removed.
Fixes#1283.
This will make things as std::to_string() and other C++ features
work with a modern and supported C++ library.
We package up libc++_shared.so and bump the revision of every C++
using package to make it rebuild against it.
Users who have built C++ using libraries or programs will probably
need to rebuild them if they are linked against Termux-supplied
libraries, as user code was previously linked against gnustl while
the system libraries are now using libc++, and it's not a good idea
to mix C++ standard libraries in a program.
