Add scripts for extracting SDKs from Command Line Tools for Xcode
Being able to extract SDKs from Command Line Tools for Xcode instead of the full Xcode package saves bandwidth, disk space, and time. Two scripts are added: * tools/gen_sdk_package_tools.sh: extracts SDKs from installed Command Line Tools on macOS (/Library/Developer/CommandLineTools) or from a path specified via XCODE_TOOLS_DIR * tools/gen_sdk_package_tools_dmg.sh: unpacks the content of provided Command_Line_Tools_for_Xcode.dmg and extracts SDKs via the above script. Tested with Command Line Tools for Xcode 12.x.

##### Packaging the SDK from Xcode Command Line Tools on macOS: #####
|

1. [Download Xcode Command Line Tools: https://developer.apple.com/download/more] \*\*\*\*
|

2. [Mount Command_Line_Tools_for_Xcode.dmg (Open With -> DiskImageMounter)]
|
||||
3. [Install "Command Line Tools.pkg" (Open With -> Installer)]
|
||||
3. Run: `./tools/gen_sdk_package_tools.sh` (from the OSXCross package)
|
||||
4. Copy the packaged SDK (\*.tar.\* or \*.pkg) on a USB Stick
|
||||
5. (On Linux/BSD) Copy or move the SDK into the tarballs/ directory of
|

OSXCross.

-- Xcode command line tools 12.x are known to work.
|
||||
|
||||
Steps 1. to 3. can be skipped if you have Xcode Command line tools
|
||||
already installed (e.g., auto-installed by running `git` or `gcc`
|
||||
command from command-line).

##### Packing the SDK from from Xcode Command Line Tools on Linux: #####

This method may require up to 25 GB of free disk space.
|
||||
An SSD is recommended for this method.
|
||||
|
||||
1. Download Xcode Command Line Tools like described in 'Packaging the SDK from Xcode Command Line Tools on macOS'
|
||||
2. Install `clang`, `make`, `libssl-devel`, `lzma-devel` and `libxml2-devel`
|
||||
3. Run `./tools/gen_sdk_package_tools_dmg.sh <command_line_tools_for_xcode>.dmg`
|
||||
4. Copy or move the SDK into the tarballs/ directory

||||
