v2 cover package/git: Fix static compilation

Hi,

This patch series fixes git package static compilation. This fixes missing library dependency coming from static library undefined symbols as well as backport of submitted and accepted git patches.

Thanks
Remi

PATCH v2 1/3 package/git: Add needed library for static compilation

Add missing ssl crypto libraries in LIBS variable used by configure.

A statically compiled libcurl need to be linked with some libraries to get all its undefined symbols resolved. Indeed when libcurl supports openssl it needs -lssl to satisfy all its dependencies, the same goes for crypto symbols.

Configure uses LIBS variable to get additional library when it compile applilcations to probe for features.

I removed the gettext part from v1 because it is not needed anymore with the git patches. But this hunk escapes my attention.

PATCH v2 2/3 package/git: Add git patch for static compilation

In reply to Remi Pommarel

Use submitted git patches that fix static compilation:
- The first patch fix library link order
- The second patch adds -lssl when needed with libcurl

These patches fix missing library in the Makefile for git compilation. configure still need additional library to be passed to LIBS variable to compile test programs for feature detection.

+Subject: [PATCH 1/3] Makefile: link libcurl before zlib
+
+For static linking especially library order while linking is important. For
+example, libcurl wants symbols from zlib when building http-push, http-fetch
+and remote-curl. So for these programs libcurl has to be linked before zlib.

PATCH v2 3/3 package/git: Used curl-config program for target

In reply to Remi Pommarel

Fix cross compilation by using curl-config script for target instead of the one from host.

+Subject: [PATCH 2/3] Makefile: make curl-config path configurable
+
+There are situations, e.g. during cross compilation, where curl-config
+program is not present in the PATH.
+
+Make the makefile use a configurable curl-config program passed through
+CURL_CONFIG variable which can be set through config.mak.
+
+Also make this variable tunable through use of autoconf/configure. Configure
+will set CURL_CONFIG variable in config.mak.autogen to whatever value has been
+passed to ac_cv_prog_CURL_CONFIG.
