Wget2 cross-compile on iOS arm64

[Jeffrey Walton]

Hi Everyone/Tim,

I've been testing iOS cross-compiles. It looks like Wget2 is having
trouble with arm64:

$ echo $CPPFLAGS
-DNDEBUG -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.2.sdk

$ echo $CFLAGS
-Wall -g2 -O3 -fPIC -arch arm64 -miphoneos-version-min=6 --sysroot
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.2.sdk

$ echo $CXXFLAGS
-Wall -g2 -O3 -fPIC -arch arm64 -miphoneos-version-min=6
-stdlib=libc++ --sysroot
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.2.sdk

$ echo $LDFLAGS

$ command -v cpp
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cpp

$ cat config.log
