Subject: tools/all_syscalls: use sh and replace awk with grep & sed
X-Git-Tag: v2.40-rc1~285^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a01065546d9613ffc9835398f56756f08a0193be;p=thirdparty%2Futil-linux.git

tools/all_syscalls: use sh and replace awk with grep & sed

using sh removes the bash dependencies, for those who don't have
bash on their system, and replaced the GNU awk with a portable
grep and sed.
