We enhance the build script (batch and bash), so it can generate
amalgamation distributions for both the UNIX and Windows platforms.
To generate a distribution for a specific version, first use make to
list all tags and check out the specified tag in the project root
directory:
$ make taglist
$ make co TAG=<tag>
Then go to the tools directory and run the script to generate tar.gz
for UNIX and generate zip for Windows:
$ cd .tag/<tag>/tools
$ ./build cleanall
$ ./build tar
$ ./build zip
Notice that this enhancement was added after the official release
v3.1.5.1c1bb23, so you need to specify a tag newer than v3.1.5.
