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.
