The system linkers provided with AIX, HP-UX, and Tru64
UNIX do not accept multiple runtime linker command-line arguments
respectively). If multiple instances are specified, only one is used.
This differs from how the Solaris and IRIX linkers work. This tool,
wrapld, is a wrapper script around the AIX, HP-UX,
and Tru64 ld command that accepts multiple runtime linker arguments
and combines them into one runtime linker argument, separating the
paths with colons.
