[Buildroot] [PATCH 8/8] toolchain: add gcc 4.6.0
Gustavo Zacarias
gustavo at zacarias.com.ar
Wed Apr 13 16:29:29 UTC 2011
Add gcc 4.6.0 to the toolchain repertoire:
Target gcc is known to be broken in some scenarios.
This version is considered experimental so things may break.

+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.
