When building gcc before libc has been installed, one gets
several warnings in libgcc2.

../../gcc/gcc/libgcc2.c: In function `__absvsi2':
../../gcc/gcc/libgcc2.c:204: warning: implicit declaration of function `abort'
For the inhibit_libc case, what about adding a decl to tsystem.h?
malloc,free,atexit are already there.
For the !inhibit_libc case, tsystem.h includes stdlib.h so problem solved.
Is there any reason why the !inhibit_libc case in tsystem.h
provides malloc,free,atexit but not abort?
