[PATCH] c6x: Fix EHTYPE relocations
R_C6000_EHTYPE relocations are implemented as GOT-indirect relocations,
but, as specified by the C6000 EABI (SPRAB89A), 13.5.1 Relocation Types,
they are a special case of SBR (static base relocation).
gcc/
* config/c6x/c6x.h (ASM_PREFERRED_EH_DATA_FORMAT): Remove the
DW_EH_PE_indirect flag.
