もうtarballをリリースしていることだし、libnmz_la_LDFLAGSの

libtool.texiのUpdating library version infomationより

Here are a set of rules to help you update your library version information: 

1.Start with version information of `0:0:0' for each libtool library. 
2.Update the version information only immediately before a public release of your software. More frequent updates are unnecessary, and only guarantee that the current interface number gets larger faster. 
3.If the library source code has changed at all since the last update, then increment revision (`c:r:a' becomes `c:r+1:a'). 
4.If any interfaces have been added, removed, or changed since the last update, increment current, and set revision to 0. 
5.If any interfaces have been added since the last public release, then increment age. 
6.If any interfaces have been removed since the last public release, then set age to 0. 

current 
The most recent interface number that this library implements. 
revision 
The implementation number of the current interface. 
age
The difference between the newest and oldest interfaces that this library implements. In other words, the library implements all the interface numbers in the range from number current - age to current.

$ ./configure --disable-shared
$ make
じゃダメですか？

make時に上書きするより、

$ CFLAGS='-02 -pg' ./configure --disable-shared

の方がいいでしょう。
