+
+On glibc the libc.so carries a copy of the math function copysignl() but
+on uClibc math functions like copysignl() live in libm. Since libgcc_s
+contains unresolved symbols, any attempt to link against libgcc_s
+without explicitely specifying -lm fails, resulting in a broken
+bootstrap of the compiler.
