toolchain: introduce BR2_TOOLCHAIN_HAS_GCC_BUG_43744

gnuradio package fails to build for the SH4 architecture with optimization
enabled with gcc 9.3.0:
http://autobuild.buildroot.net/results/1db/1db6c59c98e3c09fa13277076ee2fbe7967f1f6b/    http://autobuild.buildroot.net/results/f57/f5742e7fb6e8142bcdb53b7f4f5e9c1bea3558cd/
and I've tested it shows up with gcc 10.x and 11.x

I've commented it and supplied preprocessed file to reopen it since it was
closed with gcc 4.x:
