[parisc-linux] Building from scratch.

["Carlos O'Donell Jr." <carlos@megatonmonkey.net>]

Parisc'ers,

I was recently trying to build the toolchain from scractch on
an x86 box.

I've run into the following stumbling block:

a) glibc configure requires that I use "--enable-hacker-mode"

This really isn't documented, but It's not uncommon and I got around
it very quickly ;)

The second issue was:

b) Some strange asm problem while building glibc.

Background:

I started by building the tools, as per the instructions on the website.

- Built binutils
- Partially build gcc
- Unpack and configure kernel
- Build glibc...

At which I'm stuck. My hppa bin directory has the following built tools:
(and is on my path)

gccbug                hppa-linux-cpp      hppa-linux-objdump
gcov                  hppa-linux-gasp     hppa-linux-ranlib
hppa-linux-addr2line  hppa-linux-gcc      hppa-linux-readelf
hppa-linux-ar         hppa-linux-ld       hppa-linux-size
hppa-linux-as         hppa-linux-nm       hppa-linux-strings
hppa-linux-c++filt    hppa-linux-objcopy  hppa-linux-strip

The configure for glibc does complain about:

[snip]
checking for hppa-linux-mig... (cached) mig
configure: warning:=20
*** An auxiliary program is missing or too old;
*** some features will be disabled.
*** Check the INSTALL file for required versions.
checking whether ranlib is necessary... (cached) no
[snip]

But continues on. I've met all the requirements in INSTALL, with=20
regards to tools and their versions.

Any clues?

Cheers,
Carlos.
