Fails with:

  cpu.c:57:10: fatal error: sys/auxv.h: No such file or directory
   #include <sys/auxv.h>
            ^~~~~~~~~~~~
  compilation terminated.

From build/flac-1.3.3/src/libFLAC/cpu.c:

 56 #if defined FLAC__CPU_PPC
 57 #include <sys/auxv.h>
 58 #endif

236 static void
237 ppc_cpu_info (FLAC__CPUInfo *info)
238 {
239 #if defined FLAC__CPU_PPC
240 #ifndef PPC_FEATURE2_ARCH_3_00
241 #define PPC_FEATURE2_ARCH_3_00          0x00800000
242 #endif
243 
244 #ifndef PPC_FEATURE2_ARCH_2_07
245 #define PPC_FEATURE2_ARCH_2_07          0x80000000
246 #endif
247 
248         if (getauxval(AT_HWCAP2) & PPC_FEATURE2_ARCH_3_00) {
249                 info->ppc.arch_3_00 = true;
250         } else if (getauxval(AT_HWCAP2) & PPC_FEATURE2_ARCH_2_07) {
251                 info->ppc.arch_2_07 = true;
252         }
253 #else
254         info->ppc.arch_2_07 = false;
255         info->ppc.arch_3_00 = false;
256 #endif
257 }

Could be fixed by the following flac configure.ac patch (check for sys/auxv.h before
defining FLAC__CPU_PPC):
