+Subject: [PATCH] unix/utils/arm_arch_queries.h: fix uclibc build
+
+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:
+
+/home/buildroot/autobuild/run/instance-3/output-1/build/putty-0.80/unix/utils/arm_arch_queries.c: In function 'platform_aes_neon_available':
+/home/buildroot/autobuild/run/instance-3/output-1/build/putty-0.80/unix/utils/arm_arch_queries.c:18:22: error: 'AT_HWCAP2' undeclared (first use in this function)
+   18 |     return getauxval(AT_HWCAP2) & HWCAP2_AES;
+      |                      ^~~~~~~~~
+
+To fix this build failure, include <elf.h>
+
