Check that a working android toolchain was found

If the user selects a nonexistent ARCH, previously the call that
sets TOOLCHAINPREFIX would set it to contain a long error message,
which makes it quite hard to figure out what actually went wrong.

Instead check that CXX=$(TOLCHAINPREFIX)g++ actually points to a
working executable, and abort immediately if this isn't true.

Add dependencies to generating version.h in the object files that use it

Previously the makefile didn't know that there was any dependency between
compiling welsDecoderExt.o and welsEncoderExt.o and the regeneration
of the version.h header. This meant that in parallel builds (make -jX),
make could try to regenerate version.h while compiling welsDecoderExt.o
and welsEncoderExt.o, which would lead to errors about version.h not
existing.

Also add some spacing around the makefile rules.

This fixes parallel make building in certain cases.

Don't request executable stacks for Linux GMP plugin.

The codec seems to work without executable stack memory, and in general
executable stacks should be avoided if possible, but the assembler used
for the .asm source files requests it.  This commit adds a linker option
to override that.

Actually use iMinQp in WelRcPictureInitBufferBasedQp

This fixes a warning in certain builds, about the variable iMinQp
being set but not used. This also probably is what was intended originally.
