Current build failure on AMD64

[Fekete Zoltán <fekete.zoltan%minux.hu@localhost>]

Hi There,

My current's build breaks with the message below for 2 weeks now. Could 
you please help to resolve?

/usr/tools/lib/gcc/x86_64--netbsd/6.5.0/../../../../x86_64--netbsd/bin/ld: 
libgcc_s_pic.a(enable-execute-stack.pico): file class ELFCLASS64 
incompatible with ELFCLASS32
/usr/tools/lib/gcc/x86_64--netbsd/6.5.0/../../../../x86_64--netbsd/bin/ld:

collect2: error: ld returned 1 exit status

*** Failed target:  libgcc_s.so.1.0

Thanks in advance,
