Subject: [PATCH] Updated this if

if [[ `uname` -eq Darwin ]] ; then
    compflags=" ${compflags} -isystem /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1 -stdlib=libc++ "
fi

to work with linux bash and not always default true, thus applying the flags.

Created an if statement to prepend this

PKG_CPPFLAGS=" ${PKG_CPPFLAGS} -I"/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1""

if the uname is Darwin so it will configure under linux.
