[Bug libstdc++/38384] fails to build cross gcc for target hppa64-hp-hpux11.00 in libstdc++/libmath

["r dot emrich at de dot tecosim dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #21 from r dot emrich at de dot tecosim dot com  2009-01-14 18:47 -------
The link step for libstdc++.la gives warnings for failed file format test using
a file magic. This is wrong!

The problem results from different output of native file command and the linux
file command.
libtool uses the following regex:
"(s[0-9][0-9][0-9]|ELF-[0-9][0-9]) shared object file - PA-RISC [0-9].[0-9]"
This matches for the native file command output: 
"libm.2:         ELF-64 shared object file - PA-RISC 2.0 (LP64)"
But not for the output of the Linux file command:
"libm.2: ELF 64-bit MSB shared object, PA-RISC 2.0 (LP64) version 1, not
stripped"

Any idea how to fix this?
I think in libtool.m4 in the top directory. But I'm lost with regex
expressions.

I dont't know if the warnings at the end of this message are a result of this
issue or different one. The linker complains about fde encoding in
.libs/bitmap_allocator.o(.eh_frame) prevents .eh_frame_hdr table being created. 
There are a lot.
