gcc wants character constants to be correct. Before this change, the

following would happen on Solaris:

  m4 -B 8192 asm/des_enc.m4 > asm/des_enc-sparc.S
  gcc -DOPENSSL_SYSNAME_ULTRASPARC -DOPENSSL_NO_STATIC_ENGINE -fPIC -DOPENSSL_PIC -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -DOPENSSL_NO_KRB5 -m32 -mcpu=ultrasparc -O3 -fomit-frame-pointer -Wall -DB_ENDIAN -DBN_DIV2W -DMD5_ASM   -c -o asm/des_enc-sparc.o asm/des_enc-sparc.S
  asm/des_enc-sparc.S:2007: unterminated character constant
  asm/des_enc-sparc.S:2008: unterminated character constant
