We now configure gcc to always use the -fno-exceptions flag.
This does not affect our code since we do not use exceptions, and also
fixes the gcc port.
We now configure the gcc spec files to use a different crt files for
static & PIE binaries.
This relieves us from the need to explicitly specify the desired crt0
file in cmake scripts.
Turns out the reason GCC wasn't as smart about startup code for
shared objects as we hoped is because nobody told it to be :D
Change the STARTFILE_SPEC and ENDFILE_SPEC in gcc/config/serenity.h to
skip crt0.o and to link the S variants of crtbegin
and crtend for shared objects.
Because we're using the crtbegin and crtend from libgcc, also tell
libgcc in libgcc/config.host to compile crtbeginS and crtendS from
crtstuff.c.
