Description Mike Z 2009-11-18 20:12:58 UTC 
Although only a static file is shown, results are the same for dynamic objects.

Having selected sstrip:
mszick@deb2core:/Builds/BLDRT/buildroot$ ls -l output/target/sbin/pkgdetails
-rwxr-xr-x 1 mszick mszick 42199 2009-11-18 12:41 output/target/sbin/pkgdetails

mszick@deb2core:/Builds/BLDRT/buildroot$ file output/target/sbin/pkgdetails
output/target/sbin/pkgdetails: ELF 32-bit LSB executable, MIPS, MIPS32 rel2 version 1 (SYSV), statically linked, corrupted section header size

Having selected strip:
mszick@deb2core:/Builds/BLDRT/buildroot/output/target/sbin$ ls -l pkgdetails
-rwxr-xr-x 1 mszick mszick 46992 2009-11-18 13:38 pkgdetails

mszick@deb2core:/Builds/BLDRT/buildroot/output/target/sbin$ file pkgdetails
pkgdetails: ELF 32-bit LSB executable, MIPS, MIPS32 rel2 version 1 (SYSV), statically linked, with unknown capability 0xf41 = 0x756e6700, stripped
Comment 1 Thomas Petazzoni 2010-02-21 19:03:53 UTC 
Does the resulting file runs properly on the target or not ?

I'm not sure what sstrip does compared to strip, but it might be that sstrip strips things that confuse tools such as "file" while still allowing the program to run properly.

Quite likely fixed by http://git.buildroot.net/buildroot/commit/?id=c0e307b848d8de23e6f10a179c4f240c023c8b82
