I have built it. Slight problem is that I do not get any output as
written that I should get, something like this:

mtrace: writing to /tmp/mtrace.mtr.706

I do not see here:

LD_PRELOAD=./libmtrace.so ls
block_size_rss.c  INSTALL       mtrace.c      trace2wl.c            
trace_hist.sh
config.log        libmtrace.so  mtrace.h      trace_allocs          trace_plot.m
config.status     LICENSES      README.md     trace_allocs.c        trace_run
configure         MAINTAINERS   sample.c      trace_analysis.sh     trace_run.c
configure.ac      Makefile      statistics.c  trace_block_size_rss  trace_sample
COPYING           Makefile.in   tests         trace_dump            
trace_statistics
COPYING.LIB       malloc.h      trace2wl      trace_dump.c          util.h

But I did get something in /tmp/mtrace.mtr.XXX

So I will run Emacs that way.
