[uclibc-ng-devel] [PATCH 2/4] ldso: arc: add compiler option check

From: Sergey Matyukevich <sergey.matyukevich(a)synopsys.com> Option '-mno-long-calls' is not supported by all arc gcc compilers. For instance, this option is not supported by GCC for ARCv3 processors. Check if this option is supported before applying it.
