build: replace lowercase letters regex with POSIX character class in Makefile

Latest glibc changed some rules of sorting and regexes, the usage
likes "[a-z]" maybe not only stand for lowcase letters a..z in
different locale. Similar issues include [A-Z], [0-9] and so on.

For example, in en_US.UTF-8 locale, [a-z] means aAbBcCdD...zZ, it
stands for both of uppercase and lowercase. Currently this issue
cause `make install` fails on system with new glibc.

So use POSIX character class to instead of [...] group, something
likes [:lower:], [:upper:], [:alpha:], [:alnum:], etc... are common.
