Libtool currently uses this for piecewise linking, when the input
command-line is too long.
I believe this is portable. For sure, the following platforms support
it:
AIX 4.3.3, 5.x
HP-UX 10.20, 11.x
IRIX 6.5
RH 7.1, 9; RHEL 2.1, 3
Solaris 2.5.1-9
Tru64 UNIX 4.0D, 5.x
On IRIX, ld(1) has the following:
-r Retains relocation entries in the output file. Use of this
option is strongly discouraged.
Relocation entries must be saved if the output file is to
become an input file in a subsequent ld run. This option
also prevents final definitions from being given to common
symbols and suppresses the undefined symbol diagnostics.
This option cannot be specified in conjunction with the
-non_shared option; do not use them together on the same
command line.
