No, MinGW does not need it, as it has been enabled by default since binutils 2.36.

Apparently that change, https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=514b4e191d5f46de8e142fe216e677a35fa9c4bb, didn't apply to Cygwin but only to MinGW. But if Cygwin works with dynamicbase (I think it might have issues with it but I'm not sure?) then perhaps binutils should be changed to enable dynamicbase by default there, instead of changing compilers to pass the option by default.
