DESTDIR install on hppa-hpux

[Michael Haubenwallner]

Hi,

now I've managed to get 'make install DESTDIR=...' working on
hppa-hpux10 and hppa-hpux11 with libtool.

With this patch, 10 tests ("demo-nofast.test" to "depdemo-unst.test")
change from SKIP to PASS, and both "Simple DESTDIR install" and "DESTDIR
with in-package deplibs" (destdir.at) change from "expected failure" to
"ok", for the 32bit hppa environments marked with "*" below.
No other tests do change their result.

The most important part of the fix is already suggested in comments
around 'hardcode_minus_L=yes', as the encoded library path is used as
fallback location for a specific library when runpath lookup fails.
As this isn't really 'hardcoding' in libtool's sense, hardcode_minus_L
can safely be set to 'no' IMO, opening the door for DESTDIR support.

This does require to use 'chatr' in demo-hardcode.test to not get false
positives when testing for hardcoded path (more comments inside).

Another minor one was that there is no need to pass
"+b $install_libdir", as the linker ignores subsequent "+b" values.

The patch has been tested in these HP-UX environments (as well as on
linux and aix, without any test result changes there):

arch  HP-UX bits * compiler
------------------------------
hppa  10.20  32  * gcc-3.0.1
hppa  10.20  32  * HP C Compiler A.10.32.30 (with CXX=false)

hppa  11.11  32  * gcc-3.3.4
hppa  11.11  32  * "HP C Compiler PHCO_27774" + "HP ANSI C++ A.03.52"
hppa  11.11  64    "HP C Compiler PHCO_27774" + "HP ANSI C++ A.03.52"

ia64  11.23  32    gcc-4.2.4
ia64  11.23  32    HP aC++/ANSI C A.06.10 (both cc/aCC)
ia64  11.23  64    gcc-4.2.4
ia64  11.23  64    HP aC++/ANSI C A.06.10 (both cc/aCC

hppa  11.31  32  * gcc-4.3.1
hppa  11.31  32  * "HP C Compiler PHCO_27774" + "HP ANSI C++ A.03.85"
hppa  11.31  64    "HP C Compiler PHCO_27774" + "HP ANSI C++ A.03.85"


The patch is created and tested using recent libtool.master - I'm just
unsure about the ChangeLog heading (already inside).

Setting 'hardcode_minus_L=no' can be dropped eventually, as it is the
default and a similar comment is in demo-hardcode.test now.

Thanks!
