[OE-core] Performance issue of libtool-2.4.4

[Robert Yang]

Hello,

It seems that the new libtool (2.4.4) has increased the packages
build time, after a rough investigation, it maybe because new libtoolize
needs run a m4 command: (but libtool 2.2.2 doesn't)

     # Save the command pipeline results for further use by callers of
     # this function.
     func_extract_trace_result=`$ECHO "$_G_mini" \
       |$M4 -daq --prefix $_G_m4_traces - "$@" 2>&1 1>/dev/null \
       |$SED -n -e "$_G_transform"`

This may increase the build time (just a rough guess), I will go on
investigating on it. Does any one have any ideas, please ?
