[Buildroot] Problem with starting TI Graphics

[Peter Kuemmel <syntheticpp@gmx.net>]

Hi, 
I have problems with the package ti-gfx.

Setup uses a buildroot compiler with eabihf enabled.
All goes fine until TI's pvrsrvctl gets called:

#pvrsrvctl
/usr/bin/pvrsrvctl: line 1: syntax error: unexpected word (expecting ")")

# strace pvrsrvctl
execve("/usr/bin/pvrsrvctl", ["pvrsrvctl"], [/* 16 vars */]) = -1 ENOEXEC (Exec format error)
write(2, "strace: exec: Exec format error\n", 32strace: exec: Exec format error
) = 32
exit_group(1)                           = ?
+++ exited with 1 +++

But no problems with the modules
# lsmod
Module                  Size  Used by    Not tainted
bufferclass_ti          4734  0
omaplfb                10298  0
pvrsrvkm              157244  2 bufferclass_ti,omaplfb


First I thought it is ABI-problem so I configured the system until they match,
see below, but this didn't help.

Could it be a mis-match in the eglibc version?

# LD_TRACE_LOADED_OBJECTS=1 /usr/bin/pvrsrvctl
        libc.so.6 => /lib/libc.so.6 (0x401dc000)
        /lib/ld-linux-armhf.so.3 (0x40094000)

Many thanks for any hints!

Peter
