New Revision: 364400
URL: https://svnweb.freebsd.org/changeset/base/364400

Log:
  Fix the mips64 world build after r364284.
  
  Linking the full version of clang 11 results in errors similar to:
  
  lld: error: /usr/src/contrib/llvm-project/clang/lib/StaticAnalyzer/Frontend/AnalysisConsumer.cpp:736:(.text._ZN5clang4ento22CreateAnalysisConsumerERNS_16CompilerInstanceE+0xE0): relocation R_MIPS_CALL16 out of range: 48920 is not in [-32768, 32767]; references operator new(unsigned long)
  
  Add -mxgot to the compilation flags for llvm libraries to work around
  this error. This may be too big of a hammer, but it can always be
  refined later.
