There's a similar issue when compiling libgcc for powerpc64.
libgcc/config/rs6000/ibm-ldouble.c has these aliases:
__asm__ (".symver __gcc_qadd,_xlqadd@GCC_3.4\n\t"
".symver __gcc_qsub,_xlqsub@GCC_3.4\n\t"
".symver __gcc_qmul,_xlqmul@GCC_3.4\n\t"
".symver __gcc_qdiv,_xlqdiv@GCC_3.4\n\t"
".symver .__gcc_qadd,._xlqadd@GCC_3.4\n\t"
".symver .__gcc_qsub,._xlqsub@GCC_3.4\n\t"
".symver .__gcc_qmul,._xlqmul@GCC_3.4\n\t"
".symver .__gcc_qdiv,._xlqdiv@GCC_3.4");
Which seem to get dropped if you use -flto.
