That shouldn't be necessary.  Here's a minimal test on a clean Debian
Woody + 2.4.19 system with Solaris 8 stuff in gnemul.  usr/bin
contains Solaris binaries:

  /usr/gnemul/solaris$ $SHELL --version|head -1
  GNU bash, version 2.05a.0(1)-release (sparc-unknown-linux-gnu)
  /usr/gnemul/solaris$ bin/ls -l

There is a kernel message from running ls:
  Unimplemented Solaris syscall 131 70040000 0001b7f8 00000004 00000003
which presumably isn't important, and obviously Solaris ls is confused
about directory totals on the ext3 filesystem, but basically it just
works.  Note this is without anything like
/usr/platform/SUNW,Ultra-5_10/lib/libc_psr.so.1, which truss shows
being loaded under Solaris.

[By the way, can someone say if this is a bug?
