wrong sha512 values for 7.4.0 ?

[Oliver Kullmann]

Hello,

after download from various mirror sites I get

  > sha512sum gcc-7.4.0.tar.gz 
  6824b5c8fdb3151d8dd517911d3d975f7808525f52db32b5c25e9354b562792d6d2f1e8cc5aa019ff250df65b4f29b43f65ab6d769a070fd0015b13a3a9d6bf9
  gcc-7.4.0.tar.gz
 
however e.g.

  ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/gcc-7.4.0/sha512.sum

states:

  a86d02c2c880f46dbed04f5da8d18d9555f980c9e3b867770b2f091cf8fdba55fea34962128bd1d1e11e3694ec188d0284963c1df5d0e4a51c2da7b56cde3625
  gcc-7.4.0.tar.gz
