gcc: drop libstdc++ patch
This patch was introduced in 2010 to fix mingw compilers.
See c548c084bb
It no longer applies to gcc15 and all of our current gccs (13, 14 and 15)
build fine without it.
Tested the following cross-compilers:
```shell
nix-build --expr 'with (import ./. { }).pkgsCross.mingwW64; hello.override { stdenv = gcc13Stdenv; }' \
--expr 'with (import ./. { }).pkgsCross.mingwW64; hello.override { stdenv = gcc14Stdenv; }' \
--expr 'with (import ./. { }).pkgsCross.mingwW64; hello.override { stdenv = gcc15Stdenv; }' \
--expr 'with (import ./. { }).pkgsCross.mingw32; hello.override { stdenv = gcc13Stdenv; }' \
--expr 'with (import ./. { }).pkgsCross.mingw32; hello.override { stdenv = gcc14Stdenv; }' \
--expr 'with (import ./. { }).pkgsCross.mingw32; hello.override { stdenv = gcc15Stdenv; }'
```
