Hi Marcus (@magicus), please see the updated code which added guards to check
for GCC version >= 7.5 in
`src/java.base/linux/native/libsimdsort/{avx2-linux-qsort.cpp,
avx512-linux-qsort.cpp}`. GCC >= 7.5 is needed to compile libsimdsort using
C++17 features. Made sure that OpenJDK builds without errors using both GCC 7.5
and GCC 6.4.
