+Subject: [PATCH] unix/uxutils.h: fix build on uclibc
+
+Build on uclibc is broken since version 0.75 and commit
+65383082bf0c49cec63f4b36001a40bd9b13edf6 because AT_HWCAP2 is used
+even if <sys/auxv.h> is not available:
+
+unix/uxutils.c: In function 'platform_aes_hw_available':
+unix/uxutils.c:13:22: error: 'AT_HWCAP2' undeclared (first use in this function)
+   13 |     return getauxval(AT_HWCAP2) & HWCAP2_AES;
+      |                      ^~~~~~~~~
+
+To fix this build failure, include <elf.h>
+
+Fixes:
