Not sure why this is an issue.  This should be trivial; we do it all
the time.  You can modify LINKCOM, SHLINKCOM, LDFLAGS, and many other
vars -- see the man page.  You can do it per-OS if you like:

env=Environment()
if sys.platform == 'linux2':
  env.Append(LIBS=['xyz', 'pdq')
  env.Append(LDFLAGS=' $EXTRA_LDFLAGS')
  env['EXTRA_LDFLAGS'] = '-whatever'
if sys.platform == 'darwin':
  env[LINKCOM] = '$LINK $MYSPECIALDARWINLINKFLAGS -o $TARGET
$LINKFLAGS $__RPATH $SOURCES $_LIBDIRFLAGS $_LIBFLAGS $_FRAMEWORKPATH
$_FRAMEWORKS $FRAMEWORKSFLAGS'

etc.  Here's a tip to print all the variables in a construction environment:
env=Environment()
print env.Dump()
