[PATCH v2 0/3] add a macro to enable support of backtrace

[Wei Dai <wei.dai@intel.com>]

Some LIBC implementation like musl doesn't support backtrace( )
and backtrace_symbols declared in execinfo.h.
Currently some DPDK customers fail to build PDDK with musl.
In order to build DPDK with musl, there is a need to
reomve references toexecinfo.h.

Add a configuration parameter in config/common_linuxapp which equals to y 
by default. It also generate a macro named as RTE_EAL_ENABLE_BACKTRACE when 
this configuration paramter equals to y or no above macro when it is n.
