Hi, Maciej,
Did you build GDB on an i686-linux?  I can somehow reproduce it on
x86_64-linux, like this,

../opcodes/libopcodes.a(mips-dis.o): In function `set_default_mips_dis_options':
mips-dis.c:(.text+0x906): undefined reference to `bfd_mips_elf_get_abiflags'
collect2: error: ld returned 1 exit status
make: *** [gdb] Error 1

I configure with these options,

../binutils-gdb/configure --host=i686-pc-linux-gnu --disable-sim
--disable-binutils --disable-gprof --disa
ble-gold --disable-gas --disable-ld --enable-targets=all CFLAGS='-m32'
CXXFLAGS='-m32'

however, the build fails due to failing to find i686-pc-linux-gnu-ar.
I explicitly set AR=ar in make,
or modify libtool in several directories.  Finally, the build failed
on the error above.
