m2 build is broken on Windows

[Ludovic HOCHET]

Hello,
After getting the latest changes for m2, I get the following when
building on Windows:
$ make
Main.gmk:345: *** target pattern contains no '%'. Arrêt.
make: Nothing to be done for 'default'.

After some digging, it seem that the change "Implemented support for
Gensrc-jdk.dev.gmk in multiple repos" [1] unfortunately adds to a LIB
variable in the DeclareRecipesForPhase macro, which is initialised in
specs.gmk with Windows paths to the SDK libs directories.

Changing the call to the macro on line 162 of Main.gmk (LIB to LIB2),
then declaring LIB_TARGETS := $(LIB2_TARGETS) after the call, fixes it
for me for now.
