+Use or do not use assembler relocation operators when dealing with symbolic
+addresses.  The alternative is to use assembler macros instead, which may
+limit optimization.  The default value for the option is determined during
+GCC build-time by detecting corresponding assembler support:
+@code{-mexplicit-relocs} if said support is present,
+@code{-mno-explicit-relocs} otherwise.  This option is mostly useful for
+debugging, or interoperation with assemblers different from the build-time
+one.
