Client build fails on aarch64 because of incomplete putty source

Building the FileZilla client fails on aarch64 as observed on OpenBSD/arm64, but the problem is generic and should affect all Unix-style operating systems on aarch64 (64-bit ARM).
ld: error: undefined symbol: platform_aes_hw_available
referenced by sshaes.c
libfzputtycommon_a-sshaes.o:(aes_hw_new) in archive libfzputtycommon.a
Linking fails because the functions
The problem is in the included putty source. On aarch64 (#if HW_AES == HW_AES_NEON), the missing functions are called from sshaes.c, sshsha.c, sshsh256.c. In the original putty source, they are provided by unix/uxutils.c. However that file was omitted when the putty source was included in FileZilla.
Simply adding putty's unix/uxutils.c and adding it in Makefile.am will fix the problem.
