Nevermind, I got it working! 

Got the typeface as a bitmap array from https://github.com/susam/pcface/ , converted it to a C array of 256*14 bytes, and then used this to export it to a file:

int main(void) {
    int chr_width = 8; 
    int chr_height = 14; 
    int chr_baseline = 10; 
    PIXELFONT_U8 pixels [32 * 32]; 
    pixelfont_builder_t* builder = pixelfont_builder_create (
        chr_height, 
        chr_baseline,  
        chr_height,  
        NULL
    ); 
    unsigned char *ptr = PC_FACE_OLDSCHOOL_EGA_8X14_FONT_LIST;  
    for (int c = 0; c < 256; c ++) { 
        // Paint glyph 
        for (int y = 0; y < 14; y ++) { 
            unsigned char bitmap = *ptr ++; 
            for (int x = 0; x < 8; x ++) { 
                if (bitmap & (1 << (7 - x))) { 
                    pixels [x + chr_width * y] = 1; 
                } else { 
                    pixels [x + chr_width * y] = 0; 
                } 
            }
        }
        pixelfont_builder_glyph (builder, c, chr_width, pixels, chr_width, 0, chr_width);     
    } 
    pixelfont_t* pixelfont = pixelfont_builder_font (builder); 
    pixelfont_t* output = (pixelfont_t*) malloc (pixelfont->size_in_bytes); 
    memcpy (output, pixelfont, pixelfont->size_in_bytes); 
    FILE *pf = fopen ("ega14.fnt", "wb"); 
    fwrite (output, sizeof (unsigned char), pixelfont->size_in_bytes, pf); 
    fclose (pf); 
    pixelfont_builder_destroy (builder); 
}
