Hi developers

I finally managed to build linuxboot in Ubuntu 12.04, gcc 4.6.3
I faced some troubles so here they are to maybe help somebody

To build linuxboot apply Makefile.patch, move glibc-i686.patch and
slang.patch to linuxboot/misc.

1) make download, some links are broken

2) sf.net/.../parted-1.6.22.tar.gz file is broken, but builds without errors
$ ls -l /var/tmp/parted-1.6.22.tar.gz
-rw------- 1 slava slava 1497993 мая   21 13:52 /var/tmp/parted-1.6.22.tar.gz
$ gzip -t /var/tmp/parted-1.6.22.tar.gz
gzip: /var/tmp/parted-1.6.22.tar.gz: unexpected end of file

3) glibc does not compile, needs a patch
../sysdeps/i386/fpu/s_frexp.S: Assembler messages:
../sysdeps/i386/fpu/s_frexp.S:66: Error: invalid identifier for ".ifdef"
../sysdeps/i386/fpu/s_frexp.S:66: Error: junk at end of line, first
unrecognized character is `1'
../sysdeps/i386/fpu/s_frexp.S:66: Error: junk at end of line, first
unrecognized character is `1'
../sysdeps/i386/fpu/s_frexp.S:66: Error: Missing symbol name in directive

4) busybox, does not use CFLAGS_EXTRA
networking/udhcp/lib.a(dhcpc.o): In function `udhcpc_main':
dhcpc.c:(.text.udhcpc_main+0x5e3): undefined reference to `__fdelt_chk'

5) dosemu fails to link without additional library search path
"build-glibc-2.13/math"
/usr/lib/gcc/i686-linux-gnu/4.6/../../../i386-linux-gnu/libm.so:
undefined reference to `__get_cpu_features@GLIBC_PRIVATE'

6) slang needs a patch to compile
/usr/bin/ld: slang-2.0.7/src/objs/libslang.a(slcommon.o): undefined
reference to symbol '__libc_enable_secure@@GLIBC_PRIVATE'

7) usbutils doesn't build because libusb must know about fakelib_cflags
stage1/lib/libusb.so: undefined reference to `__fdelt_chk@GLIBC_2.15'

8) parted must be linked with libdl
../../libparted/.libs/libparted.so: undefined reference to `dlopen'
../../libparted/.libs/libparted.so: undefined reference to `dlclose'
../../libparted/.libs/libparted.so: undefined reference to `dlerror'
../../libparted/.libs/libparted.so: undefined reference to `dlsym'
