toolchain: add gcc 4.9 series

Add the recently released gcc 4.9.0.
Use 4.8.2 patches and remove those that no longer apply/are needed
(mostly PR fixes and xtensa).
libmudflap was removed upstream.

+On glibc the libc.so carries a copy of the math function copysignl() but
+on uClibc math functions like copysignl() live in libm. Since libgcc_s
+contains unresolved symbols, any attempt to link against libgcc_s
+without explicitely specifying -lm fails, resulting in a broken
+bootstrap of the compiler.
