BaseTools: Add GCC49 toolchain; align data sections to 0x40

GCC 4.9 may use 64-byte (0x40) alignment for data sections.

Therefore we use a different link script for GCC 4.9. The only
difference from the gcc4.4-ld-script is the alignment for data
sections.

When using the GCC48 toolchain with GCC 4.9, this error would be
encountered by GenFw:
> GenFw: ERROR 3000: Invalid
>   Unsupported section alignment.

edksetup.sh: Look for BuildEnv under EDK_TOOLS_PATH

EDK_TOOLS_PATH is basically a replacement for $WORKSPACE/BaseTools.

It makes sense to check for BuildEnv there, then, if $WORKSPACE
is absent but $EDK_TOOLS_PATH is present.

With this patch, it is possible to separately package tools in
/usr and use them compile EDK2 (doing "rm -rf BaseTools" in the
EDK2 tree).  This is desirable for OS distributions that need to
distribute the tools in a "free software" repository and OVMF in
a "non-free software" repository; bundling the same code in two
different packages causes confusion.  It is also simpler for distros
because the build process for BaseTools and OVMF is completely
different.

edksetup.sh: Ensure that WORKSPACE points to the top of an edk2 checkout

Since WORKSPACE should point at the EDK2 tree, the right place
to check its validity is edksetup.sh, not BaseTools/BuildEnv.

This patch makes sure that BuildEnv is always invoked with a valid
WORKSPACE.  This lets us show better error messages, and ensures that
we never dirty the user's environment.

BuildEnv will maintain backwards-compatibility and, should the variable
be missing, it will be able to set a default WORKSPACE.  Only the sanity
checks will be of lower quality.

Note that the error message in SetupEnv will never be shown if
SetWorkspace sets WORKSPACE=`pwd`.

BuildEnv: remove useless check before setting $WORKSPACE

As long as $EDK_TOOLS_PATH is properly set, the BaseTools/ directory
is not necessary in the workspace.  The BuildEnv file itself suggests
setting the variable if BaseTools/ is not available.

However, this only works if the user also sets $WORKSPACE.  Otherwise,
BuildEnv refuses to set WORKSPACE itself and does not even try to use
the preset $EDK_TOOLS_PATH.  Remove the check that fails, as it does
not have any practical benefit.
