libc/glibc: add option to force unwind
We make it an option, as not all combinations of architectures vs. compiler vs. glibc/eglibc exhibit the issue. Mostly visible on old glibc versions, it seems... This is a missing part from the glibc/eglibc merger... :-/ Signed-off-by: "Yann E. MORIN" <>

+ If your toolchain fails building while building the C library
+ start files, or the complete C library, with a message like:
+ configure: error: forced unwind support is required
+ then you may try setting this to 'y'. Otherwise, leave it to 'n'.
+ The issue seems to be related to building NPTL on old versions
+ of glibc (and possibly eglibc as well) on some architectures
+ (seen on s390, s390x and x86_64).
