[LTP] [RFC PATCH 6/6] API: Check exported symbols

[Petr Vorel]

Hi Richie,

The PR does not work few on old toolchains [1], it fails on [2]:

awk: line 1: regular expression /parse_opts ... exceeds implementation size limit

It's one of the 2 awk calls in check_export_syms.sh, I suppose the other one.
Maybe put non_prefix_syms into temporary file and then run awk on it?

Kind regards,
Petr
