Description:
The sequence:

if test "$TARGET_LINUX" = "true" -a "$static_nss" = ""
then
  tmp=`nm /usr/lib*/libc.a  | grep _nss_files_getaliasent_r`
  if test -n "$tmp"
  then
     STATIC_NSS_FLAGS="-lc -lnss_files -lnss_dns -lresolv"
     STATIC_NSS_FLAGS="$STATIC_NSS_FLAGS $STATIC_NSS_FLAGS"
     static_nss=1
  fi
fi

invokes 'nm' directly instead of $NM.  It also assumes libc is in /usr/lib*/libc.a and ignores any value $other_libc_lib might contain.

How to repeat:
Build in a cross-compilation environment.

Suggested fix:
Patch as:

if test "$TARGET_LINUX" = "true" -a "$static_nss" = ""
then
  tmp=`$NM ${other_libc_lib:-/usr/lib*}/libc.a  | grep _nss_files_getaliasent_r`
  if test -n "$tmp"
  then
     STATIC_NSS_FLAGS="-lc -lnss_files -lnss_dns -lresolv"
     STATIC_NSS_FLAGS="$STATIC_NSS_FLAGS $STATIC_NSS_FLAGS"
     static_nss=1
  fi
fi

I wonder if we could remove static nss code altogether.

Thank you for the report.

Verified as described.

      BUG#42721 configure.in invokes 'nm' directly
      
      A hardcoded use of nm and libc was put into configure.in. This broke cross-compiling and is bad practice. Fitting variables now used.

Noted in 5.1.37, 5.4.4 changelogs.

configure.in contained references to literal instances of nm and
libc, rather than to variables parameterized for the proper values on
the current platform.
[12 Aug 2009 22:42] Paul DuBois
Noted in 5.4.2 changelog because next 5.4 version will be 5.4.2 and not 5.4.4.
[15 Aug 2009 2:01] Paul DuBois
Ignore previous comment about 5.4.2.
