i have updated gcc version 4.6 5.4. clear, have both versions using sudo update-alternatives --config g++ switch between versions.

vies7605@eso9265:~/projects/u-boot/u-boot-x86$ sudo update-alternatives --config g++ there 2 choices alternative g++ (providing /usr/bin/g++).    selection    path              priority   status ------------------------------------------------------------   0            /usr/bin/g++-4.6   20        auto mode   1            /usr/bin/g++-4.6   20        manual mode * 2            /usr/bin/g++-5     20        manual mode  press enter keep current choice[*], or type selection number:   vies7605@eso9265:~/projects/u-boot/u-boot-x86$ sudo update-alternatives --config gcc there 2 choices alternative gcc (providing /usr/bin/gcc).    selection    path              priority   status ------------------------------------------------------------   0            /usr/bin/gcc-4.6   20        auto mode   1            /usr/bin/gcc-4.6   20        manual mode * 2            /usr/bin/gcc-5     20        manual mode 

i building u-boot source code(latest git version x86), gcc compiler. when using version 4.6 build fine. when use gcc version 5.4 build fails error message,

arch/x86/lib/built-in.o: in function `__wrap___udivdi3': /home/vies7605/projects/u-boot/u-boot-x86/arch/x86/lib/gcc.c:25: undefined reference `__normal___udivdi3' make: *** [u-boot] error 1 

i not sure why happening, on topic helpful.
