proj/gentoo: Initial commit

This commit represents a new era for Gentoo:
Storing the gentoo-x86 tree in Git, as converted from CVS.

This commit is the start of the NEW history.
Any historical data is intended to be grafted onto this point.

Creation process:
1. Take final CVS checkout snapshot
2. Remove ALL ChangeLog* files
3. Transform all Manifests to thin
4. Remove empty Manifests
5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$
5.1. Do not touch files with -kb/-ko keyword flags.

+Subject: [PATCH] Change _UPTi_find_unwind_table to return an integer.
+
+This keeps the definition on IA64 and all the other architectures in sync with
+the declaration of _UPTi_find_unwind_table. This also mimics the behaviour of
+what's done for local unwinding and allows the function to provide more than
+one way to undwind.

+
+ - Add tdep macro for {dwarf,ia64}_find_unwind_table so that ia64
+   doesn't try to use dwarf code.
+ - Fix extraneous #if.
+ - Fix mistyped filename in Makefile.am.
+ - Link ia64-specific tests with correct libraries.

+Subject: [PATCH] link sublibs against liblzma as needed
+
+The coredump/elf32/elf64/elfxx libs use lzma funcs but don't link against
+it.  This produces sub-shared libs that don't link against lzma and can
+make the linker angry due to underlinking like so:
+
+libtool: link: x86_64-pc-linux-gnu-gcc -O2 -march=amdfam10 -pipe -g \
+	-frecord-gcc-switches -Wimplicit-function-declaration -fexceptions \
+	-Wall -Wsign-compare -Wl,-O1 -Wl,--hash-style=gnu \
+	-o .libs/test-coredump-unwind test-coredump-unwind.o  \
+	../src/.libs/libunwind-coredump.so ../src/.libs/libunwind-x86_64.so
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_stream_footer_decode'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_index_buffer_decode'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_index_size'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_index_end'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_index_uncompressed_size'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_stream_buffer_decode'
+collect2: error: ld returned 1 exit status
+
+So add LIBLZMA to the right LIBADD for each of these libraries.
