Subject: [PATCH] configure.ac: try execinfo in libc before searching
|
|
libexecinfo
|
|
|
|
execinfo is provided by glibc, so the usual case is that it is part of
|
|
libc. Do this before starting a redundant search for libexecinfo.
|
|
|
|
This is especially relevant for cross-compilation, where
|
|
FR_SMART_CHECK_LIB can find an incompatible library.
