New Revision: 312898
URL: https://svnweb.freebsd.org/changeset/base/312898

Log:
  Add -mlong-calls also to LLVM's STATIC_CFLAGS on ARM
  
  -mlong-calls was set only in STATIC_CXXFLAGS, but there are some .c
  source files in LLVM which also need -mlong-calls.
  
  Unfortunately this is not sufficient to fix linking lldb on ARM,
  because LLVM-generated calls to __aeabi_read_tp do not honour the
  -mlong-calls flag.  See LLVM PR31769 for details.
