Hello,
gdb does not build from source any longer since gdb-multiarch packages
was enabled in 7.4.1-1. The build problems is due to a PATH_MAX issue
in gdb/nto-tdep.c:nto_init_solib_absolute_prefix(). The attached patch,
solve_PATH_MAX_issue.patch, solves this build problem. This patch has
also been submitted upstream, see
http://sourceware.org/ml/gdb-patches/2013-05/msg00878.html
Thanks!
