Julien Olivain 7af8dee3a8 package/tcl: add mandatory dependency to zlib 
Tcl changed its zlib handling in upstream commit [1]. Before this
commit, the HAVE_ZLIB macro was defined only if a zlib headers/library
was found. After that commit, the HAVE_ZLIB macro is unconditionally
defined. The only change is that: if a working zlib library is found
in the toolchain sysroot, it is used. Otherwise, the package will use
a shipped version in [2]. See also [3] and [4].

This tcl commit is included in Buildroot since commit 7fda943b43
"tcl: bump to version 8.6.1".

In Buildroot, we prefer to not use bundled libraries wherever possible,
so add an unconditional dependency to zlib.

Further notes:

This behavior leads to runtime failures, when the package is compiled
with toolchains including zlib in their sysroot. This is because at
configuration time, the package will detect zlib in the sysroot and
link against it, but the library files won't be installed on target.

This happen to be the case with Bootlin toolchains such as [5], as they
also contaions gdbserver, and since 3341ceb1e5 (package/gdb: zlib is
mandatory, not optional), we also build zlib even if only gdbserver is
built (gdbserver does not use zlib, so that's a bug in our gdb
packaging).

This toolchain also happen to be the one used in basic configurations
of the runtime test infrastructure (this issue was found while
attempting to write a runtime test for tcl).

In such cases, running "tclsh" command fails with error message:

    tclsh: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

libtcl library also miss its dependency.

    ldd /usr/lib/libtcl8.6.so
	    libz.so.1 => not found
	    libm.so.6 => /lib/libm.so.6 (0xb6dad000)
	    libc.so.6 => /lib/libc.so.6 (0xb6c65000)
	    /lib/ld-linux.so.3 (0xb6f6c000)

README 

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on OFTC IRC.
