Update to Baselibs 7.17.1, fix xgboost build

This release moves GEOS to use Baselibs v7.17.1 which mainly has a fix for NAG and ESMF. But it also changes the backing C compiler on SLES15 to GCC 11. Without this change, xgboost was not being built.

From CHANGELOG.md

Changed

• Moved to Baselibs 7.17.1
  • Fix for NAG and ESMF 8.6.0
• Update g5_modules to use GCC 11.4 as the backing C compiler on SLES 15 at NCCS
  • This was done as it was discovered that xgboost was not building on SLES15 with Intel when using GCC 12. Until xgboost can be
    updated to a newer version, this is the workaround.
