Fix posix_fadvise64 build on mips64n64
Recent binutils versions (at least 2.27) complains about libc.so when linking sotruss-lib.so with: libc.so:(*IND*+0x0): multiple definition of `posix_fadvise64@GLIBC_2.2' libc.so::(.text+0xcf940): first defined here libc.so:(*IND*+0x0): multiple definition of `posix_fadvise64' collect2: error: ld returned 1 exit status Dynamic symbols for libc.so shows (readelf --dyn-syms): 262: 000000000010b950 28 FUNC GLOBAL DEFAULT 12 posix_fadvise64@GLIBC_2.2 417: 000000000010b950 28 FUNC WEAK DEFAULT 12 posix_fadvise64@@GLIBC_2.2 1505: 000000000010b950 28 FUNC GLOBAL DEFAULT 12 posix_fadvise64@@GLIBC_2.3.3 That is, two separate definitions at version GLIBC_2.2. The issue is sysdeps/unix/sysv/linux/posix_fadvise64.c creates posix_fadvise64 weak_alias, while sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise64.c then adds compat_symbol / versioned_symbol calls. The patch remove the weak_alias definition on mips64 specific version so direct weak_alias is disabled. Checked on mips64n64 build with binutils 2.27.51.20161012. * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise64.c: Undefine weak_alias.
