85979 - Always use the -xs compiler option in Solaris debug builds.

Status: RESOLVED FIXED

(NSPR :: NSPR, defect, P2)

Right now we only use the -xs compiler option in Solaris
debug builds when we are making a binary release (i.e.,
if BUILD_NUMBER is set).  In the new world, compiler options
are set by the configure script.  We would need to add
a configure option to indicate we are making a binary release.
I think that's too much trouble.

So I am just going to always use -xs for Solaris debug builds.

Here is the documentation of the -xs compiler option.
     -xs  Disables Auto-Read for dbx. Use this option in case you
          cannot keep the .o files around. It passes the -s
          option to the assembler.

          No Auto-Read is the older way of loading symbol tables.
          It places all symbol tables for dbx in the executable
          file. The linker links more slowly and dbx initializes
          more slowly.

          Auto-Read is the newer and default way of loading sym-
          bol tables. With Auto-Read, the information is distri-
          buted in the .o files, so that dbx loads the symbol
          table information only if and when it is needed. Hence,
          the linker links faster, and dbx initializes faster.

          With -xs, if you move the executables to another direc-
          tory, then to use dbx, you can ignore the object (.o)
          files.

          Without -xs, if you move the executables, you must move
          both the source files and the object (.o) files, or set
          the path with the dbx pathmap or use command.
