Build gcc-7.1.0　gcc-7.1.0ビルド

I'll keep gcc to the latest version.　gccを最新版にしておこう。
By the way, the current gcc version of debian jessie is 4.9.2.
ちなみに、debian jessie の現在のgccのバージョンは4.9.2 である。

gmp-6.1.2 mpfr-3.1.5 mpc-1.0.3 は更新されていない

gmp-6.1.2, mpfr-3.1.5, and mpc-1.0.3 are not updated, use the last build as it is.
ので前回Buildしたのをそのまま使う。

Wow! It became a little faster? That's within the range of error.
おっ！　ちょびっと速くなった？　誤差の範囲内だな。
